using $Zn-Hg / HCl$ to

Reason $R$ : $Zn-Hg / HCl$ 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:

(1) $A$ is false but $R$ is true

(2) $A$ is true but $R$ is false

(3) Both $A$ and $R$ are true but $R$ is not the correct explanation of $A$

(4) Both $A$ and $R$ are true and $R$ is the correct explanation of $A$

Answer: (1)

Solution:

Formula: Clemmensen Reduction

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