Question

The sum of total number of carbonyl groups \((> \mathrm{C=O})\) present in the major products \(X\) and \(Y\) in the following reactions is ____.

Hint:

Important thermal reactions:
• \(\beta\)-keto acids decarboxylate easily on heating.
• Dicarboxylic acids may form cyclic anhydrides.
• Carbonyl groups include: \[ \mathrm{aldehydes,\ ketones,\ acids,\ esters,\ anhydrides} \] Always count each distinct: \[ >\mathrm{C=O} \] group carefully in the final product.

Answer 1

Correct Answer: 3
