The termination step in chlorination of methane in presence of diffused sun light is
Correct answer: C. Cl° + Cl° → Cl2
- A. Cl2 → 2Cl
- B. CH4 + Cl → CH3 + HCl
- C. Cl° + Cl° → Cl2
- D. CH3 + Cl2 → CH3Cl + Cl°
Explanation
The termination step in the chlorination of methane involves the combination of two chlorine radicals to form molecular chlorine, thereby stopping the radical chain reaction. This is represented by the equation Cl° + Cl° → Cl2.The other options do not represent the termination step accurately. Option A and Option B describe initiation and propagation steps, respectively. Option D also represents a propagation step where a methyl radical reacts with molecular chlorine.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
