Q. 14.56 - An Introduction to General, Organic, and Biological Chemistry

Question

There are four amide isomers with the molecular formula ${\mathrm{C}}_3{\mathrm{H}}_7\mathrm{NO}$. Draw their condensed structural formulas and write the IUPAC name for each. (14.6)

Step-by-Step Solution

Answer

• Amides are carboxylic acid derivatives in which the hydroxyl group has been replaced by an alkyl or aromatic group at one or more of the nitrogen groups.

The structural formula ${\mathrm{C}}_3{\mathrm{H}}_7\mathrm{NO}$ are given below:

Step 1: Introduction

That are given sentences are : 

Amides are the carboxylic acid derivatives in which the hydroxyl group

Step 2: Given information

• Amides are carboxylic acid derivatives in which the hydroxyl group has been replaced by an alkyl or aromatic group at one or more of the nitrogen groups.
• The IUPAC names of amides are formed by replacing the suffix amide with "oic acid" or "c acid (common names)" from the carboxylic acid name. The prefix N-followed by the alkyl group indicates the alkyl group attached to the nitrogen of amide.

Step 3: Explanation

That are given functional group are :

The structural formula ${\mathrm{C}}_3{\mathrm{H}}_7\mathrm{NO}$are given below:

Step 4: Explanation

The structural formula for isomers is the same. 

The following are the condensed structural formulas of isomers of the amides with the structural formulas${\mathrm{C}}_3{\mathrm{H}}_7\mathrm{NO}$ are given below:
