Question:

What is X in the following reaction? 

Show Hint

- \( KMnO_4 \) in acidic medium oxidizes alkanes to ketones or carboxylic acids. - \( Br_2 \) under UV light favors allylic or benzylic bromination in a radical mechanism.

The Correct Option is D

Solution and Explanation

Step 1: Oxidation with KMnO₄ - The given starting compound is a dicarboxylic acid. - Treatment with \( KMnO_4 \) and \( H_2SO_4 \) under heat leads to oxidative cleavage, forming a cyclic ketone. 
Step 2: Bromination with \( Br_2 \) under UV light - The cyclohexanone undergoes bromination via radical substitution at the allylic position, leading to the formation of bromo-cyclohexene.
