Question

Assertion (A): Carbon shows catenation.

Reason (R): Catenation is the property of self linking by covalent bonds.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

Options

• (1)

• (2)

• (3)

• (4)

Answer 1

(2)

Explanation:

Carbon shows catenation, i.e., it can form long chains and rings by bonding with other carbon atoms. Therefore, the Assertion (A) is true.

Catenation is the property of self-linking of atoms through covalent bonds. Therefore, the Reason (R) is also true.

However, the Reason only defines catenation and does not explain why carbon shows this property.

Hence, both A and R are true, but R is not the correct explanation of A.
