Chapter 13, Problem 13.79AP

a.

Interpretation Introduction

Interpretation:

Product that forms has to be drawn when ${{\text{(CH}}_{\text{3}}\text{)}}_{\text{2}}{\text{CCON(CH}}_{\text{3}}{\text{)}}_{\text{2}}$ is treated with water and $\text{HCl}$.

Concept Introduction:

Amide also undergo hydrolysis as like esters.  They are much less reactive than the esters.  When amide is treated with water in presence of acid as a catalyst, the product formed is carboxylic acid and ammonium salt.  General reaction can be given as follows.

    $\text{RCONHR' +}H-\text{OH}\stackrel{H-\text{Cl}}{\to }{\text{RCOOH + NH}}_{\text{3}}{\text{R'}}^{\text{+}}{\text{Cl}}^{-}$

b.

Interpretation Introduction

Interpretation:

Product that forms has to be drawn when ${\text{HO(CH}}_{\text{2}}{\text{)}}_{\text{4}}{\text{CONHCH}}_{\text{3}}$ is treated with water and $\text{HCl}$.
