Chapter 14 - Sources of Energy. Chapter 15 - Our Environment. Chapter 16 - Management of Natural Resources. Chapter 4 Science Class 10 talks about carbon compounds present universally, i. The atomic mass of Carbon is Carbon is a part of the 14th group. It is seen in both free as well as in the mixed state. Chapter 4 Science Class 10 also explains how, according to the research, it is the seventeenth most commonly found element on earth. You can find it present as coal and graphite in the elemental state.
In contrast, it is available as metal carbonates, hydrocarbons, and carbon dioxide gas in the mixed state. When it couples with other components such as chlorine, dihydrogen, dioxygen, and sulfur, it provides a fantastic range of materials that can vary from medicines tissues to.
In Class 10th Science Chapter 4, you will learn that Carbon is a unique element. It occurs in several forms. Two examples of pure Carbon are coal and soot.
You will see some forms of Carbon which are considered pure and then some forms which are not pure like coal. It is the mixture of both Carbon and hydrogen.
It is soft to touch and is dark grey or black in appearance. Longest chain of the carbon chain will be considered as a parent chain.
From which branch seems to close the main chain numbering will start from them 3. We will use prefixes if we find more than one branch like tri, tetra etc. Alphabetical order should be maintained. Chemical Properties of Carbon and its Compounds A.
Combustion reaction:- A lot of Carbon and its compounds on its reaction with oxygen leads to the evolution of large amount of carbon dioxide and heat this reaction is also known as oxidation reaction.
Oxidation reaction:- The Carbon and its Compounds on heating undergoes compete oxidation that means it add more oxygen in it one of the classic example of this scenario when alcohols are reacted with potassium paramagnet it completely oxidize into carboxylic acid.
Addition reaction:- This reaction is use in the hydrogenation means addition of hydrogen in oils, in this reaction the unsaturated hydrocarbons are converted into saturated hydrocarbon by making them react with hydrogen in the presence of nickel as catalyst D.
Substitution reaction:- If we substitute or replace any atom or a group of atoms from any reaction and substitute it with any other atom then the reaction is known as substitution reaction. Esters are easily formed by esterification reaction which is a reaction between alcohol and acid in this ethanol and carboxylic acid esters are sweet smelling compounds.
This compound is used in the preparation of perfumes and sweet smelling compounds. What are organic and inorganic Carbon compounds?
For e. What is alkane, alkene, alkyne Classification of Hydrocarbon? What are saturated organic compound and Unsaturated Organic carbon and its compounds? Alkene:-having double bond, E. What are the Properties of making carbon compounds? Tetravalency:-Since it cannot take part in electron configuration so Carbon has decided to share with other elements without losing much energy. What is catenation:-way of making direct bonding with elements in branch chain and long chain or ring chain between same elements in an infinite number of elements or compounds.
Polymerisations:-Process of making long chain of element by adding no. For example:-Ethene converts into polythene and ester into polyester. Solution: It is a class of chemical reactions in which the net result is addition of hydrogen H 2 to unsaturated organic compounds such as alkenes, alkynes, etc. Hydrogenation is widely applied to the processing of vegetable oils and fats.
Complete hydrogenation converts unsaturated fatty acids to saturated ones. From the above hydrocarbons C 2 H 2 is an alkyne, whereas C 3 H 6 is an alkene. So, C 3 H 6 and C 2 H 2 will undergo addition reactions. Question 21 Give a test that can be used to differentiate chemically between butter and cooking oil. Solution: Bromine water test can be used to differentiate chemically between butter and cooking oil. Add bromine water to a little of cooking oil and butter taken in separate test tubes.
Decolourising of bromine water by cooking oil unsaturated compound b. Butter saturated compound does not decolourise bromine water. Question 22 Explain the mechanism of the cleaning action of soaps. Solution: We all know that soap is used to remove dirt and and grime from substances. Generally dirt and grime get stuck because they have an oily component, which is difficult to remove, by plain brushing or washing by water. A soap molecule has two parts, a head and a tail i. A soap molecule has a tadpole like structure shown below.
The organic part is water insoluble but is soluble in organic solvents or in oil or grease. The ionic part is soluble in water, as water is a polar solvent. When soap is added to water in which dirty clothes are soaked, the two parts of the soap molecule dissolve in two different mediums.
When the clothes are rinsed or agitated, the dirt gets pulled out of the clothes, by the soap molecule. In this way soap does its cleaning work on dirty and grimy clothes or hands. The micelle pulls out the dirt and grime more efficiently. Question 23 Would you be able to check if water is hard by using 10th Ncert Carbon And Compounds Korea a detergent? Solution: We would not be able to check whether a sample of water is hard by using a detergent, this is because a detergent forms lather easily even with hard water. Question 24 People use a variety of methods to wash clothes.
Solution: It is necessary to shake to get clean clothes because the soap micelles, which entrap oily or greasy particles on the surface of dirty clothes, have to be removed from their surface. When the clothes which are wet by soap solution are beaten, the micelles containing oil or greasy dirt particles get removed from the surface of dirty clothes and go into water and the dirty cloth gets cleaned. Question 1. Buckminster fullerene is an allotropic form of [NCERT Exemplar] a phosphorus b sulphur c carbon d tin Answer: c Buckminster fullerene is an allotrope of carbon containing clusters of 60 carbon atoms joined together to form spherical molecules.
Its formula isC 60 C-sixty. It is a dark solid at room temperature and as compared to another allotropic form of carbon diamond and graphite , it is neither very hard nor soft. Question 2. Question 3. In which of the following. Question 4. The long hydrocarbon chain is hydrophobic water repelling and ionic portion is hydrophilic water attracting. Question 5.
Its formula is C 6 H 6. In structure b formula is C 6 H In structure a double bond is not at alternate position. Question 6. Which of the following is not a straight chain hydrocarbon?
Rest three are straight chain hydrocarbons. Question 7. Which among the following are unsaturated hydrocarbons? Both ii and iv structures have triple and double carbon-carbon bonds respectively.
Question 8. Chlorine reacts with saturated hydrocarbons at room temperature in the [NCERT Exemplar] a absence of sunlight b presence of sunlight c presence of water d presence of hydrochloric acid Answer: b Chlorine reacts with saturated hydrocarbon at room temperature in the presence of sunlight.
Question 9. In the above given reaction, alk. Question Butanone is a four carbon compound with functional group [NCERT Exemplar] a carboxylic acid b aldehyde c ketone d alcohol Answer: c In butanone, the functional group is. Which of the following does not belong to the same homologous series? Thus, C 4 H 10 is the next member of this series. So, C 4 H 8 does not belong to the homologous series.
Which of the following are correct structural isomers of butane? Since, molecular formula is same, only structures are different. So, i and iii are isomers while structures ii and iv have molecular formulaC 4 H 8. In a soap micelle, the soap molecules are arranged readily with hydrocarbon ends directed towards the centre and ionic ends directed outwards. Oils on treating with hydrogen in the presence of palladium or nickel catalyst form fats.
This is an example of [NCERT Exemplar] a addition reaction b substitution reaction c displacement reaction d oxidation reaction Answer: a Oils are unsaturated compounds containing double bonds. Addition reactions are characteristic property of unsaturated hydrocarbons.
The given reaction is an example of addition reaction. Carbon forms four covalent bonds by sharing its four valence electrons with four univalent atoms, e. Atomic number of Ne is Its electronic K L configuration is 2,8. Therefore, after the formation of four bonds, carbon attains the electronic configuration of neon. Mineral acids are stronger acids than carboxylic acids because i mineral acids are completely ionised.
While cooking, if the bottom of the vessel is getting blackened on the outside, it means that [NCERT Exemplar] a food is not cooked completely b the fuel is not burning completely c fuel is wet d fuel is burning completely Answer: b The unburnt particles of the fuel present in smoke blacken the vessel from outside. The reaction in which a reagent partially or completely replaces atom or group of atoms from saturated compounds or A are called B reaction.
Here, A and B respectively refers to a unsaturated compounds, addition b unsaturated compounds, substitution c benzene, substitution d alkene, addition Answer: c Substitution reaction is usually given by saturated compounds 10th Ncert Carbon And Compounds Yield and benzene. Unsaturated compounds usually give addition reactions.
Which structure do the ester compounds in the table have in common? Answer: d All esters have the common structure of carboxylic group represented by the suffix date. Carbon is an important constituent of the foods, fuels, household and commercial articles, textile fabrics, perfumes, explosives, dyes, war gases etc. Allotropes of Carbon An element, in different forms, having different physical properties but similar chemical properties is known as allotropes of that element.
Carbon has three well known allotropes which are graphite, diamond and buck minster fullerene. Fullerene: This is another class of carbon allotropes. The first one to be identified was C which has carbon atoms arranged in the shape of a football.
Since this looked like the geodesic dome designed by the US architect Buckminster Fuller, the molecule was named fullerene. Unsaturated hydrocarbons: Compounds consist of a single, double or triple bond between carbon-carbon atoms.
Cycloalkanes: These hydrocarbons possess one or multiple carbon rings. The hydrogen atom is attached to the carbon ring. Aromatic hydrocarbons: These are also called as arenes.
Arenes are compounds which consist of at least one aromatic ring. Soaps: Ester of higher fatty acids is called soap. It is manufactured by the reaction of caster of higher fatty acid with sodium hydroxide. The sodium salt so formed has cleansing property. Detergents: Soap cannot form lather in hard water. To overcome this problem, detergents were introduced.
Detergent is also known as soapless soap. Detergent is sodium salt of benzene sulphonic acid or sodium salt of long chain alkyl hydrogen sulphate. Oxidation Reactions: Though combustion is generally an oxidation reaction, not all oxidation reactions are combustion reactions. Oxidation is also carried out by using oxidizing agents Oxidants. Addition reactions: Unsaturated organic compounds, like alkenes and alkynes, undergo addition reactions to become saturated in nature. Substitution reactions are single displacement reactions.
