Chapter 26, Problem 26.14P

Interpretation Introduction

Interpretation:

The steps in the reaction in Equation 26-29 are addition of a nucleophile to a polar double bond and two proton transfer steps. The mechanism for this reaction is to be drawn.

Concept introduction:

In nucleophilic addition step, the electron-rich atom acts as a nucleophile and attacks the electron-poor carbon, and the shared electron pair becomes a lone pair. In proton transfer step, the positively charged atom having H atom is deprotonated. In the next proton transfer step, the negatively charged atom is protonated.
