Question

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

• A. $sp$ and $s{p}^2$
• B. $s{p}^2$ and $s{p}^3$
• C. sp3 and $s{p}^2$
• D. sp3 and sp3

Answer 1

Answer: (B)

$s{p}^2$ and $s{p}^3$

The states of hybridisation of boron and oxygen atoms in boric acid $\left(H_{3}B{O}_3\right)$ are respectively are $s{p}^2$ and $s{p}^3$
respectively.

In boric acid the boron is surrounded by three bond pair thus it shows $s{p}^2$ hybridization while oxygen is surrounded by one two bond pair and two lone pairs so it shows $s{p}^3$ hybridization.
