Bromobenzene

Bromobenzenes are a group of halobenzenes formed in a substitution reaction between bromine and benzene with a hydrogen bromide biproduct. The name strictly refers to monobromobenzene, a benzene with a single bromine; however it can be used to refer to a benzene containing any number of bromine molecules. Bromobenzene is a clear pale yellow liquid.
