What is X in the following reaction?





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.
In the given circuit, if the potential at point B is 24 V, the potential at point A is:
