Question: Draw the products of each reaction. Assume excess halogen is present.

Short Answer

Expert verified

Answers

The products formed in the given reactions are shown below.

Step by step solution

01

Halogenation in bases

Halogenation is carried out by treating a carbonyl compound that has alpha hydrogens with a halogen in the presence of a base. When excess halogens are present, all the possible acidic protons get replaced with halides.

02

Mechanism involved in the halogenation in bases

The first step involves the abstraction of the proton by the base. The second step is the formation of an enolate. The third step involves the attack of enolate on electrophile in the presence of the base.
