What is the word equation for the reaction between methane and bromine?

The correct word equation for the reaction between methane and bromine is "Methane + Bromine -> Bromomethane + Hydrogen bromide." This reaction represents a halogenation process, where bromine (a halogen) reacts with methane to produce bromomethane, which is an alkane derivative, along with hydrogen bromide (HBr), a compound resulting from the interaction of methane's hydrogen atoms with bromine.

In this context, methane (CH4) has one or more of its hydrogen atoms replaced by bromine, leading to the formation of bromomethane (CH3Br). The byproduct of this substitution reaction is hydrogen bromide, demonstrating how a halogen can effectively replace a hydrogen atom in the hydrocarbon structure. This type of reaction is typical in organic chemistry, particularly in the reactions of alkanes with halogens.

The other options do not accurately describe the reaction that takes place between methane and bromine. For instance, option A introduces water, which is not a product of this specific halogenation reaction. Option C incorrectly involves chlorine instead of bromine, thus misrepresenting the halogen involved. Option D suggests that bromine is a byproduct rather than a reaction participant, which does
