Homework Answers
Lewis acids are those species which can accept a lone pair of electrons.
BF3 (g) + F1- (g) = BF41- (g)
In the given reaction, BF3 (g) acts as a Lewis acid. It has vacant p-orbitals on B-atom. So it can accept a lone pair of electrons from F1-. Here F1- is Lewis base.
Therefore, the correct option is----
C. BF3 (g)
