Chapter 21.8, Problem 25P

Interpretation Introduction

Interpretation:

The structure for the product with molecular formula ${\text{C}}_{\text{3}}{\text{H}}_{\text{5}}{\text{N}}_{\text{3}}\text{O}$ that is formed by the reaction of acrolein and sodium azide in aqueous acetic acid is to be drawn. The reason that the reactivity difference between acrolein and propanal is to be explained.

Concept Introduction:

>

If a molecule contains two electrophilic sites, then during the attack of the nucleophile, the competition occurs between the two electrophilic sites.

>

Strong nucleophile prefers to attack the strong electrophile site, and weak nucleophile prefers to attack the weak site of the electrophile.
