Question

Assertion (A): Carbon element forms a very large number of carbon compounds (or organic compounds).

Reason (R): The two characteristic properties of carbon element which lead to the formation of a very large number of carbon compounds (or organic compounds) are (i) catenation (self-linking), and (ii) tetravalency (four valency).

Options

• Both A and R are true and R is correct explanation of the assertion.

• Both A and R are true but R is not the correct explanation of the assertion.

• A is true but R is false.

• A is false but R is true.

Answer 1

Both A and R are true and R is correct explanation of the assertion.

Explanation:

Carbon forms a vast number of organic compounds due to its unique chemical properties. Catenation allows carbon atoms to link together in long, stable chains or rings, while its tetravalency enables it to bond strongly with four other atoms simultaneously. Therefore, the reason directly and accurately explains why the assertion is true.
