Question

Benzioc Acid reacts with LiAlH$_4$ to give :

• A. Ethylene
• B. Methyl Benzene
• C. Phenol
• D. Benzyl Alcohol

Hint:

LiAlH$_4$ is strong enough to reduce acids, esters, and ketones to alcohols. It does not reduce the benzene ring itself under normal conditions.

Answer 1

The Correct Option is D

Lithium Aluminium Hydride (LiAlH$_4$) is a strong reducing agent.
It reduces carboxylic acids (-COOH) directly to primary alcohols (-CH$_2$OH).
The reaction is: C$_6$H$_5$COOH $\xrightarrow{\text{LiAlH}_4}$ C$_6$H$_5$CH$_2$OH.
The product C$_6$H$_5$CH$_2$OH is named Benzyl Alcohol.
