Question

True statement for the above compounds is:

• A. (a) is phenol while (b) is alcohol
• B. Both (a) and (b) are primary alcohol
• C. (a) is primary and (b) is secondary alcohol
• D. (a) is secondary and (b) is primary alcohol

Answer 1

Answer: (D)

(a) is secondary and (b) is primary alcohol

In compound (a), the hydroxyl group is attached to secondary carbon atom. Hence, it is secondary alcohol.

In compound (b), the hydroxyl group is attached to primary carbon atom. Hence, it is primary alcohol.

A primary carbon atom is attached to one other carbon atom whereas a secondary carbon atom is attached to two other carbon atoms.

Therefore, the option is D.
