Question

Question: What product is formed when acetic acid is treated with each reagent: (a)${\mathbf{CH}}_{\mathbf{3}}{\mathbf{NH}}_{\mathbf{2}}$ ; (b) ${\mathbf{CH}}_{\mathbf{3}}{\mathbf{NH}}_{\mathbf{2}}$, then heat; (c) ${\mathbf{CH}}_{\mathbf{3}}{\mathbf{NH}}_{\mathbf{2}}$ + DCC?

Short answer

Answer

a.

b.

c.

Step-by-step solution

Step-by-Step SolutionStep 1: Reaction of the carboxylic acid with amines

The carboxylic acids react with the amines to form the amides. These reactions are an example of nucleophilic acyl substitution reactions.

The reaction of carboxylic acids with the primary amines forms the secondary amides.

The reaction of acetic acid with the given reagents is as follows:

a. The reaction of the acetic acid with the primary amine

Product formation with reagent a.

b. The reaction of the acetic acid with the primary amine and then heat forms the secondary amide.

Product formation with reagent b.

c. The reaction of the acetic acid with the primary amine in the presence of DCC also forms the secondary amide.

Product formation with reagent c.
