Chapter 10.10B, Problem 10.23P

(a)

Interpretation Introduction

To determine: The flaw in the given incorrect Grignard synthesis.

Interpretation: The flaw in the given incorrect Grignard synthesis is to be stated.

Concept introduction: Grignard reagent will be protonated by the groups like $\text{OH},\text{NH},\text{SH}$ and $\text{C}\equiv \text{CH}$. The groups which are attacked by the Grignard reagent are $\text{C}=\text{O},\text{C}=\text{N},\text{S}=\text{O},\text{N}=\text{O}$ and $\text{C}\equiv \text{N}$. Grignard reagent are incompatible with acid or water.
