Q. 14.40 - 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) Pentanamide is formed when pentanoic acid reacts with ammonia. In this reaction, a water molecule is destroyed.

(part b) Structural diagram:

(part c) $N-$anilinepropanamide is formed when propanoic acid reacts with aniline.

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).

Pentanamide is formed when pentanoic acid 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).

Step6: Given Information (part c).

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

Step7: Explanation (part c).

$N-$anilinepropanamide is formed when propanoic acid reacts with aniline.
