In which of the following molecules/ions

\mathrm{B}{\mathrm{F}_3},\mathrm{NO}_2^ - ,\mathrm{NH}_2^ -

, and

{\mathrm{H}_2}\mathrm{O}

the central atom is

s{p^2}

hybridized?

View answer and explanation

Correct option: A

\mathrm{B}{\mathrm{F}_3}\mathrm{and NO}_2^ -

Option A (

\mathrm{B}{\mathrm{F}_3}\mathrm{and NO}_2^ -

) is correct because both

BF_3

and

NO_2^-

have central atoms with three

sp^2

hybrid orbitals.
