Question

Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason $R$
Assertion A :

can be easily reduced using $Zn - Hg / HCl$ to

Reason R :**** $Zn \cdot Hg / HCl$ is used to reduce carbonyl group to $- CH _2-$ group.

In the light of the above statements, choose the correct answer from the options given below:

• A. A is false but $R$ is true
• B. Both A and $R$ are true but $R$ is not the correct explanation of $A$
• C. A is true but $R$ is false
• D. Both A and R are true and $R$ is the correct explanation of $A$

Answer 1

Answer: (A)

A is false but $R$ is true

Answer 2

The correct answer is (A) : A is false but R is true

The acid sensitive alcohol group reacts with HCl , hence Clemmenson reduction is not suitable for above conversion.
