In the first propagation step of the free radical chlorination of methane, which of the following occurs?

A) Cl₂ dissociates.
B) A chlorine radical abstracts a hydrogen.
C) A carbon radical reacts with Cl₂.
D) A carbon radical reacts with a chlorine radical.

Free Radical

An atom, molecule, or ion that has an unpaired valence electron, making it highly reactive and prone to participating in chemical reactions.

Chlorination

The process of adding chlorine to water or organic molecules, either for disinfection purposes or to introduce chlorine atoms into molecules for chemical synthesis.

Propagation Step

A part of a chain reaction where intermediates react with the original reactants to produce more intermediates and products, continually propagating the reaction.
