Question

Compound (A) reacts with sodium metal to form one mole of H2. The compound (A) can be
Options
A CH3CH2CH=CH2
B HOCH2CH2CH2CH2OH
Correct Answer
C CH=CH–CH=CH2
D CH3CH2CH2CH2OH
Correct Answer

Option B is the correct answer.

Detailed Explanation

A diol (HOCH2CH2CH2CH2OH) has two -OH groups, so it reacts with sodium metal to produce one mole of H2 per mole of compound (since each -OH gives 1/2 H2). The other options have only one or zero -OH groups.

Hint

Which compound has two -OH groups?
