• Versatile nature of carbon.
• Allotropes of carbon.
• Saturated and unsaturated carbon compounds.
• Chains, branches and rings in carbon compounds and Isomers.
• Functional groups.
• Homologous series.
• Nomenclature of carbon compounds.

What is common in all the members of a family carbon and its compounds?

All the members in a particular homologous series of family have the same characteristic functional group. For example, in organic acids, the functional group is carboxyl group (—COOH). Any two consecutive members in a particular family have the same common difference of CH2 in their molecular formulae.

Why carbon is poor conductor of electricity?

Carbon Compounds for Poor Conductor Electricity As carbon has been found in the covalent form in nature and its free electron has been used for their covalent bond. For this reason, the electricity does not flow due to the absence of free electrons.

What is carbon and its compounds Chapter 4?

Topics and Subtopics in NCERT Solutions for Class 10 Science Chapter 4 Carbon and its Compounds: A piece of black electrode used in dry cell on strong heating in air gave a colourless gas which turned lime -water milky. What was the material of the electrode?

What are the extra questions for Class 10 science?

Extra Questions for Class 10 Science Chapter 4 Carbon and its Compounds with Answers Solutions Question 1. Draw the electron dot structure of the gas molecule which is liberated when zinc metal is treated with aqueous NaOH solution. Question 2. Write the number of covalent bonds in the molecule of ethane. Question 3.

How many types of carbon compounds are there?

It can form double and triple bond compounds. There exist three types of carbon chains viz, branched, ring and straight. Carbon is considered as a major source of fuel. Ethanoic acid and ethanol are carbon compounds which are important and used in our daily lives.

Why does carbon form large number of compounds?

(a) Carbon forms large number of compounds since carbon is small in size and can form stable covalent bonds (catenation) and it shows tetravalency. (b) Air holes of gas burner are made open (adjusted) so that air can pass through, which is needed for complete combustion, so that heated vessels do not get blackened.
