Step-by-step solution

Oxidation of this substituted ketone will give a ketone and a carboxylic acid. This reaction takes place by the cleavage of carbon atoms near the carbonyl carbon and the nearby carbons. This cleavage can be from both the sides of carbonyl carbon thus producing two different carboxylic acids and ketones. The ketone formed converts to hydrocarbon in the presence hydrazine in alkaline medium. The overall reaction is shown below.

‘A’ and ‘B’ in the above reactions are:
