Chapter 17, Problem 17.12P

Interpretation Introduction

(a)

Interpretation:

Whether the given compound gives the same product, different product or no reaction on oxidation with PCC and ${\text{MnO}}_{\text{2}}$ is to be predicted.

Concept introduction:

The oxidizing agent PCC oxidizes primary alcohols to aldehyde and secondary alcohols to ketones. On the other hand, ${\text{MnO}}_{\text{2}}$ is a selective oxidizing agent. It oxidizes allylic and benzylic hydrogens. Primary allylic alcohols are oxidized into aldehydes whereas secondary allylic alcohols are oxidized into ketones on treatment with ${\text{MnO}}_{\text{2}}$.
