Q. 14.39 - An Introduction to General, Organic, and Biological Chemistry

Question

Draw the condensed structural or line-angle formula for the amide formed in each of the following reactions:

a.

b.

c.

Step-by-Step Solution

Answer

(part a) Ethanamide is formed once ethanol reacts with ammonia. A molecule of water is destroyed in this reaction.

part (b) When ethanolic acid reacts with ethylamine, $N-$ethyl ethanamide is formed 

(part c) $N-$propyl benzamide is formed when benzoic acid interacts with propylamine.

Step1: Introduction. (part a)

Amides are carboxylic acid derivatives wherein the hydroxyl group is changed with an amine. Amidation is a reaction that occurs once carboxylic acid reacts with a substrate. 

A water molecule is removed in this reaction, as well as the carboxylic acid but also amine molecules combine to form the amide.

Step2: Given Information (part a).

To develop a condensed structural or line-angle method for the specified reactions.

Step3: Explanation (part a).

Ethanamide is formed when ethanol reacts with ammonia. In this reaction, a water molecule is destroyed.

Step4: Given Information (part b).

To develop a condensed structural or line-angle method for the specified reactions.

Step5: Explanation (part b).

$N-$ethyl ethanamide is formed when ethanolic acid reacts with ethylamine.

Step6: Given Information (part c).

To develop a condensed structural or line-angle method for the specified reactions.

Step7: Explanation (part c).

$N-$propyl benzamide is formed when benzoic acid interacts with propylamine.
