Question

Which of the following conversions can be carried out by Clemmensen Reduction?

Answer 1

Clemmensen reduction

In Clemmensen reduction, aldehydes and ketones are reduced to their corresponding alkanes on reaction with zinc amalgam and hydrochloric acid.


Analysing the options

Option A:

Benzaldehyde into benzyl alcohol

Benzaldehyde cannot be converted into benzyl alcohol using Clemmensen reduction. It will give Toluene on reaction with $Zn-Hg/HCl$

Option B:

Cyclohexanone can be coverted into cyclohexane by Clemmensen reduction.

Option C:

Benzoyl chloride into benzaldehyde

Benzoyl chloride cannot be converted into benzaldehyde by Clemmensen reduction.

Option (D)

Benzophenone into diphenyl methane

Benzophenone can be coverted into diphenylmethane by Clemmensen reduction.


Hence, options B and D are the correct answers.
