Question

CH3COCH3 react with zn-HgHCl

Answer 1

Answer:

Clemmensen Reduction. The reaction of aldehydes and ketones with zinc amalgam (Zn/Hg alloy) in concentrated hydrochloric acid, which reduces the aldehyde or ketone to a hydrocarbon, is called Clemmensen reduction.

Answer 2

When $CH_{3} COCH_{3}$ reacts with $Zn-H_{g}HCL$ it results in a Clemmensen reduction.

Definition of Clemmensen Reduction:

• It is a reaction used to reduce the number of ketones or aldehydes to alkanes with the use of hydrochloric acid and zinc amalgam.
• The Clemmensen Reduction was named after Erik Christian Clemmensen, a Danish chemist.

Mechanism of Reduction:

There are two types of proposals for the mechanism of this reduction:

1. Carbanionic mechanism: This shows that protonated carbon is directly attacked by zinc.
2. Carbenoid mechanism: This method is a radical one, and the happenings on zinc metal surfaces are reduced. In this method, reduction happens at the surface of a zinc catalyst.
