Classify the following species into Lewis acids and Lewis bases and show how these act as Lewis acid`//`base:
a. `overset(Θ)(O)H, b. F^(Θ), c. H^(o+), d. BCl_(3)`

Explanation

(a) `OH^(-)` is a Lewis base since it can donate its lone pair of electrons.
(b) `F^(-)` is a Lewis base since it can donate a pair of electrons.
(c) `H^(+)` is a Lewis acid since it can accept a pair of electrons.
(d) `BCl_(3)` is a Lewis acid since it can accept a pair of electrons.
