Step by step solution

01

Step-by-Step Solution Step 1: Tautomerism in amides

Tautomerism is the phenomenon of the interconversion of a single compound into two forms. A hydrogen atom changes its position in the course of this process.

Amides are known to show tautomerism. The two structures that are formed are shown below:

Tautomerism in amides

Out of the two tautomers, the amide tautomer is more stable. Hence, amides tend to stay at their amide tautomer form.

02

Tautomerism in the given amides

a. The tautomerism in the given amide is shown below:

Tautomers of compound a.

b.

The tautomers of the given amide are shown below:

Tautomers of compound b.

c.

In this case, the forward direction is more favored since the more stable tautomer is formed.

Tautomers of compound c.
