Chapter 19, Problem 19.31P

Interpretation Introduction

Interpretation:

The curved-arrow mechanism for the acid-catalyzed hydrolysis of the imine derivative from benzaldehyde and ethylamine is to be predicted.

Concept introduction:

The imine is a kind of organic compound which is formed by the reaction of a carbonyl compound with an amine. The general formula of the imine compound is ${\text{R}}_{\text{2}}\text{C}=\text{NR}$. The general reaction for the formation of imine is shown below.

${\text{R}}_{\text{2}}\text{C}=\text{O}+{\text{NH}}_{\text{2}}\text{R}\to {\text{R}}_{\text{2}}\text{C}=\text{NR}+{\text{H}}_{\text{2}}\text{O}$

The imines can undergo hydrolysis reaction to form carbonyl compound and an amine.
