`H_(3)BO_(3)` is.

A

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 central boron atom in boric acid `H_(3)BO_(3)` is electron deficient i.e. boric acid is a lewis acid with one p-orbitals 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.
