Chapter 20, Problem 36P

Interpretation Introduction

Interpretation:

The synthesis of each of the given compounds by using ethanol and sodium or potassium cyanide as the sources of carbon atoms and any other necessary inorganic reagents is to be shown.

Concept introduction:

${\text{KMnO}}_{\text{4}}$ acts as an oxidizing agent. Oxidation of primary alcohols by ${\text{KMnO}}_{\text{4}}$ results in the formation of carboxylic acids.

Reaction of carboxylic acids with thionyl chloride results in the formation of acid chlorides.

The full form of PCC is pyridiniumchlorochromate. It acts as a mild oxidizing agent.

It oxidizes primary alcohols into aldehyde and secondary alcohol into ketones.
