Chapter 17, Problem 25P

Interpretation Introduction

Interpretation:

The products formed when propanamide reacts with the given compounds are to be identified.

Concept introduction:

Amides are compounds that have a nitrogen group attached to the carboxylic carbon of the organic acid. Here, nitrogen with no organic substituent is simply called amide, whereas nitrogen having any substituent is denoted with N, N- prefixes according to isomerism.

When propanamide reacts with water, it undergoes base-catalyzed ester hydrolysis to give carboxylic acid and ammonium ion.

When propanamide reacts with water and an ${\text{HO}}^{-}$ ion, it undergoes acid-catalyzed ester hydrolysis to give carboxylate ion and ammonia.

When propanamide reacts with ${\text{P}}_{\text{4}}{\text{O}}_{\text{10}}$ in the presence of heat, it forms nitrile.
