Chapter 10, Problem 10.30P

Interpretation Introduction

(a)

Interpretation:

The product expected when $\text{propane-1, 3-diol}$ reacts with pyridinium chlorochromate (PCC) is to be stated.

Concept introduction:

Primary and secondary alcohols can be oxidized into aldehydes and ketones using $\text{Cr(VI)}$ compounds as they are very good oxidizing agents. Few forms of chromium used to oxidize are chromate $\left({\text{CrO}}_{\text{4}}^{2-}\right)$ and dichromate $\left({\text{Cr}}_{\text{2}}{\text{O}}_7^{2-}\right)$ and chromium trioxide $\left({\text{CrO}}_{\text{3}}\right)$. Primary alcohols are oxidized into aldehydes and secondary alcohols are oxidized into ketones.

Interpretation Introduction

(b)

Interpretation:

The product expected when $\text{3-(2-hydroxyethyl)-1-methylcyclobutanol}$ reacts with pyridinium chlorochromate (PCC) is to be stated.
