Chlorination of methane begins with homolysis of Cl2 because:
ALight ionises C-H bonds
BCl2 is a polar molecule
CCl-Cl is weaker than C-H
DC-H is weaker than Cl-Cl
Answer & Solution
Correct answer: C. Cl-Cl is weaker than C-H
The Cl-Cl bond is weaker than the C-C and C-H bonds, so light breaks it first.
