Question

The state of hybridization of boron and oxygen atoms in boric acid$\left(H_{3}B{O}_3\right)$ are respectively:

• A. sp³ and sp³
• B. sp² and sp³
• C. sp³ and sp²
• D. sp² and sp²

Answer 1

The correct option is B

sp² and sp³

Solution: Boron atoms in this molecule are $s{p}^2$ hybridised and oxygen atom shows $s{p}^3$ hybridization, each oxygen atom also having two lone pairs of electrons on it.
