Interpretation: The mechanism for the given reaction between an alkene and bromine molecule in the presence of light is to be stated.
Concept introduction: A molecule that does not possess a charge and contains an unpaired electron is termed as free radical. Free radicals are highly reactive material, but they have a short life span.
The reaction that includes the addition of one or more bromine atoms in a compound is known as bromination reaction. Bromination reaction is a type of halogenation reaction.

- Consider this reaction: Br CH;OH Br-Br H3CO The mechanism proceeds through a first cationic intermediate, intermediate 1. Nucleophilic attack leads to intermediate 2, which goes on to form the final product. In cases that involve a negatively charged nucleophile, the attack of the nucleophile leads directly to the product.
