We’re being asked to predict the reaction between AlCl3 and NH3 in a solvent that does not participate as a reactant.


We know that AlClproduces the same effect as the addition of H+.  


Recall that, in neutralization reactions, adding an His similar to donating a proton  → by definition, an acid is a proton donor


This means that AlCl3 acts like an acid but since it does not have an H+ → we will use the Lewis definition of acids and bases.


Based on the Lewis definition:


Lewis acid is an electron pair acceptor.

Some characteristics of a Lewis acid:

When hydrogen is connected to an electronegative element such as P, O, N, S or halogens

▪ hydrogen gains a partially positive charge → makes hydrogen act as a Lewis acid

Positively charged metal ions
