Chapter 23, Problem 23.13YT

Interpretation Introduction

Interpretation:

The mechanism for the reaction in Equation 23-39 is given, but the curved arrows have been omitted. The missing curved arrows are to be supplied, and the name of the elementary step is to be written below each reaction arrow.

Concept introduction:

The curved arrows show the movement of electrons from electron-rich to electron-poor atoms. In each step, the bonds are broken and formed. The protons are involved in proton transfer step. The nucleophilic elimination step involves the formation of $\text{π}$ bond. Nucleophilic addition step involves the breaking of $\text{π}$ bond.
