Question

d. + kmno₄ (aq) →

Explanation:

Step1: Benzene stability

Benzene is a highly stable aromatic compound due to its delocalized $\pi$-electron system. The $KMnO_4$ is a strong oxidizing agent.

Step2: Oxidation resistance

Aromatic compounds like benzene do not undergo oxidation by $KMnO_4$ under normal conditions because the oxidation would disrupt the aromaticity which is energetically unfavorable.

Answer:

No reaction occurs.
