Q. 14.73 - An Introduction to General, Organic, and Biological Chemistry

Question

Draw the condensed structural or line-angle formulas for the products from the hydrolysis of each of the following: (14.6)

Step-by-Step Solution

Answer

When $\mathrm{HCl}$ is added the hydrolysis products are carboxylic acid and the ammonium acid

part a) 

part  b) 

part  c)   

part  

Step 1: Given information (part a)

That are given sentences are : 

Amides are derivatives of carboxylic acid 

Step 2: Explanation (part a)

Amides are carboxylic acid derivatives in which the hydroxyl group is replaced with an amine. Amidation is a reaction that occurs when carboxylic acid reacts with a substrate. A water molecule is removed in this reaction, and the carboxylic acid and amine molecules combine to form the amide.

Amides go through a hydrolysis reaction in which a water molecule is added to the amide to split it. When $\mathrm{HCl}$is added the hydrolysis products are carboxylic acid and the ammonium salt.

Step 3: Given information (part a)

That are given structural are: (a)

N-methylethanamide undergoes acid hydrolysis

Step 4: Explanation (part a)

N-methylethanamide undergoes acid hydrolysis and produce ethanoic acid and methylammonium chloride.

Amides go through a hydrolysis reaction in which a water molecule is added to the amide to split it. The hydrolysis products of NaOH are carboxylate salts and ammonia or an amine.

Step 5: Given information (part b)

That are given structural are :(b)

Methanamide undergoes base hydrolysis and produce sodium methanoate and ammonia.

Step 6: Explanation(part b)

Methanamide undergoes base hydrolysis and produce sodium methanoate and ammonia.

Step 7: Given information (part c)

That are given structural are : (c)

Propanamide undergoes acid hydrolysis

Step 8: Explanation (part c)

(c) Propanamide undergoes acid hydrolysis and produce propanoic acid and ammonium chloride.
