In SO₂, NO₂⁻ and N₃⁻, the hybridizations at the central atom are respectively :

Hybridization in SO2, NO2− and N3− | JEE Main PYQ | Chemical Bonding

In SO₂, NO₂⁻ and N₃⁻, the hybridizations at the central atom are respectively:

(A) sp², sp² and sp²

(B) sp, sp² and sp

(D) sp², sp² and sp

Correct Answer: sp², sp² and sp

Explanation

SO₂: Central sulfur has three electron domains (two bonds + one lone pair), hence sp² hybridization.

NO₂⁻: Central nitrogen has three electron domains, therefore sp² hybridization.

N₃⁻: Central nitrogen has two electron domains, resulting in linear geometry and sp hybridization.
