Step-by-step solution

Introduction (Part a)

Amides are carboxylic acid variants in which the hydroxyl group has been replaced with an amine. Amidation is a reaction that occurs when carboxylic acid reacts with a substrate. A water molecule is removed in this reaction, and also the carboxylic acid and amine molecules combine to form the amide.

Given Information (part a).

To Enter the IUPAC name here.

Explanation (part a).

Because the ethyl complex is formed to the nitrogen atom in this structure, the prefix $N-$ comes before the name amide. $N-$ethyl ethanamide is the IUPAC name for this structure.

Given Information (part b).

Explanation (part b).

This structure has three carbon atoms. Propanamide is the IUPAC name for this structure.

Given Information (part c).

To Enter the IUPAC name here.

Explanation (part c).

This structure has four carbon atoms, with a methyl group attached to the third carbon atom. The compound's IUPAC name is $3-$methyl butanamide.
