Explanation / Answer

Benzene is the Lewis base

Bromonium ion( Br+ ) is the Lewis acid

Lewis acid is the species which can accept a pair of electrons.

Lewis base is the species which can donate a pair of electrons.

In the given reaction, benzene donates a pair of electrons to Bromide ion.

Therefore benzene acts as Lewis base and bromonium ion (Br+) acts as Lewis acid.
