11.1

i. Why and how carbon complete its octet?

Ans. Carbon complete its octet to achieve stability. And it complete its octet by completing its tetra-valency.

ii. Point out the properties of carbon which are responsible for the formation of long chains of carbon atom in organic compounds?

Ans. These properties are:

1.      Catenation.

2.      Isomerism.

3.      Strength of covalent bonds of carbon

4.      Multiple Bonding.

iii. Why the melting and boiling points of organic compounds is low?

Ans. The melting and boiling point of organic compounds is low because, covalent bond is present b/w them. It is a very weak bond.

iv. Why the organic compounds are poor conductor of electricity?

Ans. Organic compounds are poor conductor of electricity because covalent bonding is present b/w them and they do not forms ions in water. So, they are poor conductor.

v. What are the reasons for the formation of millions of organic compound?

Ans. The main reasons for the formation of millions of organic compound is isomerism, catenation, strength of covalent bonds in carbon and multiple bonding. These properties are not present in in-organic compounds. They are the cause of formation of many organic compounds.
