Question

The hybridization of boron and oxygen atoms in boric acid are respectively :

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

Answer 1

Answer: (B)

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

B has 3 bond pairs of electrons and oxygen has 2 lone pairs and 2 bond pairs of electrons in boric acid. Hence, hybridization of boron is $s{p}^2$ and that of oxygen is $s{p}^3$.
