Final answer:

The suggested mechanism involves radical-chain chlorination for forming chlorocyclohexane through light-initiated reaction.


Explanation:

Suggested Mechanism for Light-Initiated Reaction of Cyclohexane with Chlorine:

To form chlorocyclohexane through a light-initiated reaction, a plausible mechanism involves radical-chain chlorination. Here is a step-by-step mechanism:

  1. Initiation: Cl2 + Light → 2Cl·
  2. Propagation: Cl· + Cyclohexane → Cyclohexyl· + HCl, followed by Cyclohexyl· + Cl2 → Chlorocyclohexane + HCl

This mechanism involves the initiation of radicals through light and the propagation steps where cyclohexane reacts with chlorine radicals to form chlorocyclohexane.
