H(3)BO(3) is :...

`H_(3)BO_(3)` is :

A

Monobasic and weak Lewis acid

B

Monobasic and weak Brddotosted acid

C

Tribasic and weak Brddotosted acid

D

Monobasic and strong Lewis acid

Text Solution

Verified by Experts

The correct Answer is:
A
`H_(3)BO_(3) + overset(Theta)OH rarr B(OH)_(4)^(Theta) + H^(o+)`
`H_(3)BO_(3)` is a monobasic acid. It accept lone pair of electrons and thus acts as weak Lewis acid.
