Question

Quizplus · Accepted Answer

The given reaction involves the reaction of cyclohexene with Cl₂ in presence of light. The reaction proceeds via a radical mechanism which involves the following elementary steps:
1. Bond homolysis: Cl₂ (in presence of light) undergoes homolysis to give two chlorine radicals.
Cl₂ → 2Cl•
2. Radical addition: A chlorine radical attacks the pi-electrons of the double bond in cyclohexene and forms a cyclohexyl radical.
Cl• + C₆H₁₀ → C₆H₁₀Cl•
3. Bimolecular homolytic substitution: Another chlorine radical attacks the cyclohexyl radical and replaces the hydrogen atom present on the cyclohexyl radical with a chlorine atom.
Cl• + C₆H₁₀Cl• → C₆H₁₀ClCl
Therefore, option B is the correct choice since electrophilic addition is not involved in the given radical reaction.
