Question

Which of the following statements about $H_{3}B{O}_3$ is not correct?

• A. It is strong tribasic acid
• B. It is prepared by acidifying an aqueous solution of borax
• C. It has a layer structure in which planar $B{O}_3$ units are joined by hydrogen bonds
• D. It behaves as Lewis acid

Answer 1

The correct option is A It is strong tribasic acid

$H_{3}B{O}_3$ is a monobasic Lewis acid which is prepared b acidifying an aqueous solution of Borax.

In the planar structure of $H_{3}B{O}_3$, $B{O}_3$ units are joined by Hydrogen bonds.

Hence, Option "A" is the correct answer.
