प्रश्न
Why chlorination of methane is not possible in dark?
Advertisements
उत्तर
- Chlorination of methane is a free radical substitution reaction.
- Before chlorine reacts with methane, the Cl-Cl single bond must break to form free radicals and this can only be done in the presence of ultraviolet light.
- In dark, chlorine-free radicals formation is not possible and so chlorination of methane is not possible in dark.
- The ultraviolet light is a source of energy and is being used to break of Cl-Cl and produce Cl free radical Free radicals which can attack methane. in dark, this is not possible.
