Chapter 21, Problem 21.52P

Interpretation Introduction

Interpretation:

A complete, detailed mechanism for the given reaction is to be drawn.

Concept introduction:

The general mechanism of a nucleophilic addition-elimination reaction consists of two steps. First, a nucleophile attacks the electron-poor atom of a $\text{π}$ bond in a nucleophilic addition step, producing a high-energy intermediate. Second, the intermediate eliminates a leaving group initially bonded to the electron-poor atom of the $\text{π}$ bond.
