Hybridization of S in SO₂:
Asp³d
Bsp
Csp³
Dsp² (trigonal planar; one lone pair on S, two bonded O's)
Answer & Solution
Correct answer: D. sp² (trigonal planar; one lone pair on S, two bonded O's)
SO₂: S has 1 LP + 2 σ bonds (with O's). sp² hybridization. Bent geometry. Resonance gives S-O bond order = 1.5.
