Question

Which is more acidic BF3 or AlCl3?

Answer 1

Explanation:

BF3 is less acidic than AlCl3 as there much stronger pi-backbonding between the Boron and Fluorine atoms while there is no backbonding in AlCl3 as well. The tendency of boron to accept electrons from the base, is way lesser than that of Al...

Answer 2

Answer:

Boron is more electronegative than aluminium, therefore boron has more tendency to attract electrons. It means that BF3 behaves more like Lewis acid than AlCl3.
