MCQ
Halogenation of alkanes is an example of
- AElectrophilic substitution
- BNucleophilic substitution
- ✓Free-radical substitution
- DOxidation
✓
Answer
Correct option: C.
Free-radical substitution
c
Halogenation of alkanes is carried out in the presence of photochemical conditions.
Halogenation of alkanes is carried out in the presence of photochemical conditions.
Under photochemical conditions, the halogens will break homolytically and forms radical. The halogen radical will abstract hydrogen from alkanes. Now the alkyl radical can combine with alkyl radical or it can also combine with halogen radical forming alkyl radicals.
