monobasic and weak Lewis acid.

B

monobasic and weak Bronsted acid.

C

monobasic and strong Lewis acid.

D

tribasic and weak Bronsted acid.

Text Solution

Verified by Experts

The correct Answer is:
A
The boron atom in boric acid, `H_(3)BO_(3)` is electron deficient i.e., boric acid is a Lewis acid with one `p^(-)` orbital vacant. There is no d-orbital of suitable energy in boron atom. So, it can accommodate only one additional electron pair in its outermost shell.
