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: $Zn - Hg / HCl$ 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:

Aicharya · Accepted Answer

Clemmensen reduction: The carbonyl group of aldehydes and ketones is reduced to ${CH}_{2}$ group on treatment with zinc-amalgam and concentrated hydrochloric acid.

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

So, assertion is false but reason is true.
