Q42. - Organic Chemistry

Question

Question: Draw a stepwise mechanism for the following reaction.

Step-by-Step Solution

Answer

Answer

 

The stepwise mechanism of the haloform reaction is shown below.

Step 1: Haloform reaction

Halogenation is carried out by treating a carbonyl compound with alpha hydrogen atoms with a halogen in the presence of a base. When excess halogens are present, all the possible acidic protons get replaced by halogens. This reaction is known as the haloform reaction.

Step 2: Mechanism involved in the haloform reaction

The first step is the abstraction of a base. The second step is the formation of an enolate, followed by the third step that is the attack of an electrophile in the presence of a base.
