Q. 14.74 - An Introduction to General, Organic, and Biological Chemistry

Question

4 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

Part (a) N-ethyl ethanamide is hydrolyzed by a base to produce sodium ethanoate and ethylamine.

Part (b) Methanamide is acid hydrolyzed, yielding Methanolic acid and ammonium chloride.

Part (c) Pentalamide is hydrolyzed by a base, yielding sodium pentanoate and ammonia.

Part (a) Step 1: Introduction

The fundamental definitions and properties of lines, as well as angles, are provided. It will provide students with a basic understanding of these geometrical terms. Lines are broadly classified as follows: Angles are broadly classified as follows: A line segment is a section of a line with two ends.

Step 2: Amides are derivatives

Amides are carboxylic acid derivatives in which the hydroxyl group is replaced with an amine. Amide is formed when carboxylic acid reacts with a substrate in a reaction known as amination. 

A water molecule is removed in this reaction, and the carboxylic acid and amine molecules combine to form the amide.

Step 3:Given data

Amides go through a hydrolysis reaction in which a water molecule is added to the amide to split it. When ammonium salt is added, the hydrolysis products are carboxylic acid and ammonium salt.

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

Part (a) Step 4:N-ethyl ethanamide undergoes base hydrolysis

a)N-ethyl ethanamide is hydrolyzed by a base to produce sodium ethanoate and ethylamine.

Part (b) Step 5: Methanamide undergoes acid

b) Methanamide is acid hydrolyzed, yielding Methanolic acid and ammonium chloride.

Part (c) Step 6:Pentalamide undergoes base

c) Pentalamide is hydrolyzed by a base, yielding sodium pentanoate and ammonia.
