Question

Chlorination of methane does not occur in dark because (A) methane can form free radicals in presence of sunlight only (B) to get chlorine free radicals from Cl2 molecules energy is required. It cannot happen in dark (C) substitution reaction can take place only in sunlight and not in dark (D) termination step cannot take place in dark. It requires sunlight

Tardigrade Admin · Accepted Answer

Chlorination of methane is free radical substitution. to get chlorine free radical energy is required which is provided by sunlight to initiate the reaction.

C l_{2} \to h v Cl \cdot + Cl \cdot

Q. Chlorination of methane does not occur in dark because

methane can form free radicals in presence of sunlight only

to get chlorine free radicals from $C l_{2}$ molecules energy is required. It cannot happen in dark

substitution reaction can take place only in sunlight and not in dark

termination step cannot take place in dark. It requires sunlight

Chlorination of methane is free radical substitution. to get chlorine free radical energy is required which is provided by sunlight to initiate the reaction.
