BF3 and NF3

[Mason_Aguila_2G]

Are BF3 and NF3 both electrophiles? Why/Why not?

[Shruti Amin 1E]

Boron has an empty 2p orbital and a strong positive charge on the boron atom (because Fluorine is electronegative)

So yes, BF3 is an electrophile.

Unlike BF3, NF3 is a Lewis Base, and it won't accept electron pairs from other species.

That's my understanding of it, but I could be wrong.

BF₃ is an electrophile because it has an empty p orbital that can accept electrons. In contrast, NH₃ has a lone pair that can do chemistry. As such, NH₃ is a nucleophile.
