Chapter 18, Problem 26P

Interpretation Introduction

Interpretation:

N containing functional groups of benazepril should be identified as amine or amide and it should be classified as $1^0,2^0\text{ or }{3}^0$.

Concept Introduction:

Amine − is an organic N compounds formed by replacing one or more H atoms of ${\text{NH}}_{\text{3}}$ . Amines are classified as $1^0,2^0\text{ or }{3}^0$ by the number of alkyl groups bonded to the N atom.

  $1^0$ amines - Consist only one $\text{C}-\text{N}$ bond

  $2^0$ amines- Consist two $\text{C}-\text{N}$ bonds

  $3^0$ amines- Consist three $\text{C}-\text{N}$ bonds

Amide- is an organic compound contains the group of $-{\text{C(O)NH}}_{\text{2}}$ , formed from ammonia by replacing one or more H atoms.

  $1^0$ amides - Consist only one $\text{C}-\text{N}$ bond

  $2^0$ amides- Consist two $\text{C}-\text{N}$ bonds

  $3^0$ amides- Consist three $\text{C}-\text{N}$ bonds
