The reaction mechanism of alkanes with halogens is known as;
Correct answer: B. Free radical substitution
- A. Propogation
- B. Free radical substitution
- C. Addition
- D. Elimination
Explanation
Free-radical halogenation is a type of halogenation. This chemical reaction is typical of alkanes and alkyl-substituted aromatics under application of UV light and the reaction mechanism is known as free radical substitution. The reaction is used for the industrial synthesis of chloroform (CHCl3), dichloromethane (CH2Cl2), and hexachlorobutadiene. Addition, propagation and elimination are the three steps of free radical substitution.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
