Chapter 20, Problem 20.55P

Interpretation Introduction

(a)

Interpretation: The Grignard reagent and aldehyde (or ketone) needed to prepare the given alcohol are to be predicted and the all possible routes are to be drawn.

Concept introduction: One should follow the retrosynthetic pathway to find out the Grignard reagent and aldehyde (or ketone) needed to prepare an alcohol. This involves two steps. The first step is finding of carbon bonded to the $\text{OH}$ group in the product. The second step is cleaving the molecule into two parts; Grignard reagent, and carbonyl.
