a)

b)

c)

d)

Short answer

Part a)

Part b)

Part c)

Part d)

Step-by-step solution

step - 1 Introduction (Part a)

• Carboxylic acids are completely neutraliZed when they react with strong bases like NAOH and KOH to generate carboxylate salts.
• By substituting the ic acid (at the end) with ate, the carboxylate ion is called.

step - 2 Given information (part- a)

Potassium propanoate is the carboxylate salt generated when propanoic acid reacts with KOH.

step-3 Explanation (part-a)

• In the presence of an acid catalyst, a carboxylic acid combines with an alcohol to produce esters, known as esterification.
• The OH group of the acids and the OH group of the alcohols mix and are eliminated as a water molecule in this process.

step-4 Given information (part-b)

The products of the reaction have the following condensed structural formula:

step-5  Explanation (part-b)

step-6 Given information (part-c)

The line-angle formula for the reaction's products is,

Step-7 Explanation  (part-c)

Step-8 Given information (part-d)

• Amides are carboxylic acid derivatives in which the hydroxyl group has been replaced with an amine.
• Amidation is a process in which carboxylic acid combines with a substrate to produce amide.
• A water molecule is removed in this reaction, and the carboxylic acid and amine molecules unite to produce the amide.

Step-9  Explanation  (part-d)

The condensed structural formula for the reaction's products is
