Class 10 Science Ncert Solutions Chapter 4. Carbon and its Compounds Important Topics
Carbon compounds are defined as chemical substances containing carbon. More compounds of carbon exist than any other chemical element except for hydrogen. … In general bonds of carbon with other elements are covalent bonds. Carbon is tetravalent but carbon free radicals and carbenes occur as short-lived intermediates.
Their varied properties are only because of the different arrangement of the carbon atoms. In fact, the entire field of organic chemistry is based on carbon and the bonds it forms. The study of chemistry carbon and its compounds is undoubtedly essential for understanding the elements available around us.
The four major categories of organic compounds that are present in all living things are carbohydrates, lipids, proteins and nucleic acid.
Some of the most important compounds of carbon are carbon dioxide (CO2), carbon monoxide (CO), carbon disulfide (CS2), chloroform (CHCl3), carbon tetrachloride (CCl4), methane (CH4), ethylene (C2H4), acetylene (C2H2), benzene (C6H6), acetic acid (CH3COOH), and their derivatives.
Carbon is basis for all living organisms and a versatile element. It is tetravalent and has the property of catenation. Carbon forms covalent bonds with oxygen, chlorine, hydrogen, nitrogen sulphur and itself. It can form double and triple bond compounds. There exits three types of carbon chains. Carbon is considered as a major source of fuel.

Question : When the bottom of the vessel is getting blackened on the outside while cooking, it shows that
- The food is cooked completely.
- The fuel is not burning completely.
- The food is not cooked.
- The fuel is burning completely.
- ) The bottom of the vessel is getting blackened on the outside, then it means that the fuel is not burnt completely.
Question : Explain the nature of the challenge bond using the bond formation in CH3Cl.
Carbon is tetravalent in nature. In the outermost she’ll, carbon have four electrons removal of these electrons needs more energy and gain the four electrons needs more energy. To complete the octet, carbon needs to share the four electrons with other carbon atoms or different atoms. Carbon forms one bond with chlorine and three bonds with hydrogen.
Question : What is homologous series? Explain with an example.
A homologous series is a series of carbon compounds that have some chemical properties but different physical properties and the differences between two successive compounds is -CH2.
For example : Alkanes family. The general formula of Alkane is CnH2n+2.
Question : How can ethanol and ethanoic acid be differentiated on the basis of their physical and chemical properties?
Chemical properties :
Ethanol is alcohol and ethanoic acid is carboxylic acid. When alcohol and carboxylic acid reacts with carbonates and bicarbonate than only carboxylic acid reacts with carbonates and bicarbonates and evolve the CO2 gas that turns lime water milky.
Physical properties :
The melting point of ethanol is – 114.1 degree C and ethanoic acid is 16.6 degree C. Ethanoic acid melting point is below the room temperature it freezes during winters. Ethanol is liquid at room temperature but ethanoic acid is solid at room temperature Ethanol has pleasant smell and ethanoic acid is vinegar smell.
Question : In the electrolytic refining of a metal M, what would you take as the anode, the cathode and the electrolyte?
In the electrolytic refining of a metal M:
Anode à Impure metal M
Cathode à Pure metal M.
Electrolyte à Solution of salt of the metal M.
Question : Why are carbon and it’s compound used as fuels for most applications?
When the saturated carbon compounds burnt with air form a carbon dioxide, water with lot of energy and light. In this reaction no smoke will produce section less pollution. It is exothermic process. It is used as fuels because high calorific value.
Question : Explain the formation of scum when hard water is treated with soap.
Soaps are the sodium or potassium salt of long chain of carboxylic acid. Hard water contains the chloride and sulphates of calcium and magnesium. When soap will add in the hard water form less lather so some amount of salt is unused. This insoluble salt is known as scum.
Question : What change will you test soap with litmus paper?
Soap is basic in nature so red litmus turns blue but blue litmus remains same.
Question :12 What is hydrogenation? What is it’s industrial applications?
The addition of hydrogen on the unsaturated compounds are known as hydrogenation. It is a addition reaction in the presence of Ni/Pt/Pd as catalyst. Unsaturated compounds convert into saturated compounds. Through this process the vegetable oil is converted into ghee.
Question : Which of the following hydrocarbons undergo addition reactions:
Unsaturated hydrocarbons undergo addition reactions The unsaturated hydrocarbons general formula is CnH2n-2 or CnH2n.
I’m the given compounds C3H6 and C2H2 undergo addition reactions while C2H6, C2H8 and CH4 are saturated hydrocarbons.
Question : Give a test that can be used to differentiate chemically between butter and cooking oil.
Cooking oil is unsaturated fats but butter is saturated. By hydrogenation, oil will reacts but butter will not reacts.
Question : Explain the mechanism of the cleaning action of soaps.
Cleansing action of soaps:
Soap contains the two parts. One part is hydrophobic and the other is hydrophilic. Soaps are the sodium or potassium salt of long chain of carboxylic acid. When the dirty clothes dip in the soap solution, the hydrophobic ends attach the dirt and form a big cluster. This cluster is known as micelle and trap the dirt.
Que. What is the electron dot structure of carbon dioxide
Ans. Cross dot structure of CO2.
Que. How many structural isomers possible for permanent?
Three structural isomers for pentane.
Que. What are the two properties of carbon to form a large number of compounds?
The two properties of carbon to form a large number of compounds are:
- Catenation – It is ability to form a bond with itself. It is the self linking ability
- Tetravalency – Carbon can make only four bonds. That arrangement of the atoms are known as tetravalency.
Que. Why is mixture of ethyne and air is not used?
When ethyne is burnt in air, it gives a sooty flame due to unsaturation nature. If ethyne is burnt with oxygen, it gives a clear flame with temperature 2500 degree C because of complete combustion. Oxy-acetylene flame is used for welding. It is difficult to attain this much high temperature without mixing oxygen that’s why a mixture of ethyne and air is not used.
Que. Distinguish experimentally between an alcohol and carboxylic acid.
When alcohol and carboxylic acid reacts with carbonates and bicarbonates and evolve the CO2 gas that turns lime water milky.
Que. What are oxidising agents?
An oxidizing agent is a reactant that removes electrons from other reactants during a redox reaction For example: Alkaline potassium permanganate and acidified potassium dichromate.
