Answer:
AlCl3.Structure 2 can be classified as both a Brønsted–Lowry and a Lewis base.
Explanation:
Let us recall that a Lewis acid is a lone pair acceptor while a Lewis base is a lone pair donors.
A Brownstead-Lowry acid is a proton donor while a Brownstead-Lowry base is a lone pair acceptor.
NH3 functions as a Lewis base because it can donate it's lone pairs in coordinate covalent bonding.
It can also accept a proton thereby acting as a Brownstead-Lowry base in the formation of the NH4+ ion.
