At room temperature and pressure, bromine reacts with benzene, in the presence of a halogen carrier to produce bromobenzene. This is an electrophilic substitution reaction.
The electrophile is the bromonium ion, Br+ and is generated when bromine reacts with the halogen carrier, e.g. AlBr3.
Complete the mechanism in Fig. 1.1 to show how the bromonium ion is produced by adding any full and partial charges and curly arrows.

Complete the mechanism in Fig. 1.2 to show how bromobenzene is produced from Br+ and benzene. Include any relevant charges and curly arrows.
