A

`BF_(3)`

B

`AlCl_(3)`

C

`SO_(2)`

D

`H_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
D
According to Lewis, bases are substances which have unshared pair of electron and can donate the electron pair to the formation of coordinate covalent bond. Hence `H_(2)O` is a Lewis base. Whereas `BF_(2).AlCl_(3) and SO_(2)` are Lewis acid.
