Question: 4. What are the two properties of carbon which lead to the huge number of carbon compounds we see around us?

Solution:

Carbon can form huge number of carbon compounds because of the following properties:

(a) Catenation: Carbon can form bond with other carbon atoms. This property is called catenation. Because of catenation, carbon can form long chains, branched chains and closed chains.

(b) Carbon can form compounds with elements of many other elements.
