Draw a mechanism for the reaction of ammonia with cyclohexane carboxylic acid. In the box to the left, draw any necessary curved

kirill115 [55]

Answer:

Answer is attached but read below for full explanation.

Explanation:

This reaction is called Hydrolysis of Amides. Amides are carboxylic acid derivatives where the -OH of the carboxylic acid has been replaced by -NH2, -NHR, or -NR2 of an amine. Since the reaction between a carboxylic acid and an amine to give an amide also liberates water, this is an example of a "condensation reaction".
