Interpretation Introduction

Interpretation:

The structure of an aldehyde, ${\text{C}}_{\text{8}}{\text{H}}_{\text{8}}{\text{O}}_{\text{2}}$ which on oxidation by ${\text{KMnO}}_{\text{4}}$ gives terephthalic is to be stated.

Concept introduction:

Oxidation is a type of reaction in which addition of oxygen atom or removal of hydrogen atom takes place. It occurs by loss of electrons. The substance which gets reduced in a reaction is called the oxidizing agent. The carbonyls get oxidized to give carboxylic acids.
