Classify the following species into Lewis acids and Lewis bases and show how these act as such:
(a) `HO^(-)` , (b) `F^(-)` , (c ) `H^(+)` , (d) `BCl_(3)`

Explanation

a. `overset(ddotΘ)overset(":"OH)` is a Lewis base as it can donate an electorn pair.
b. `(":" underset (ddot)(ddot F^(Ӫ)))` ion acts as Lew is base as it can donate any one of the its `4` lone pairs.
c. `H^(o+)` ion is Lewis acid as it can accept a lone pair of electrons from bases such as `overset(Θ)OH` and `F^(Θ)` ions.
d. `BCI_(3)` acts as Lewis acid as it can accept a lone pair of electrons from species such as `ddotNH_(3)` or `R ddot NH_(2)` (amine) molecules.
