Answer:
See explanation
Explanation:
Even though the question is incomplete, but I believe you want to know the Lewis acid and Lewis base in the reaction; AlBr3+NH3⇌H3NAlBr3.
A Lewis acid is a lone pair acceptor while a Lewis base is a lone pair donor.
If we look at the reactants, AlBr3 has an open sextet hence it must be a lone pair acceptor ( a Lewis acid). NH3 is a lone pair donor owing to the lone pair present on nitrogen atom, hence it a Lewis base.
The reaction can be classified as a an acid-base reaction according to the Lewis definition of acids and bases.
