Question

The hybridisation of boron and oxygen atom in boric acid $H_{3}B{O}_3$ are respectively:

• A. $s{p}^{2}andsp$
• B. $s{p}^{2}ands{p}^3$
• C. $s{p}^{2}ands{p}^2$
• D. $s{p}^{3}ands{p}^3$

Answer 1

The correct option is B $s{p}^{2}ands{p}^3$

In $H_{3}B{O}_3$, boron is attached to three oxygen atoms and each oxygen atom is attached to a hydrogen atom.
Each oxygen has two lone pairs. Boron is $s{p}^2$ hybridised and oxygen is $s{p}^3$ hybridised
