Number of species from the following in which the central atom is sp ^3 hybridized and the molecule/ion has a bent (V-shaped) geometry is: H ₂ O , NH ₂⁻, OCl ₂, I ₃⁻, SO ₂, NO ₂⁻

Step-by-step solution

For H ₂ O : Central atom O has 6 valence electrons. It forms 2 bonds and has 2 lone pairs. Steric number = 4 ( sp ^3 ). Geometry is bent. For NH ₂⁻ : Central atom N has 5 valence electrons + 1 (charge) = 6. It forms 2 bonds and has 2 lone pairs. Steric number = 4 ( sp ^3 ). Geometry is bent. For OCl ₂ : Central atom O has 6 valence electrons. It forms 2 bonds and has 2 lone pairs. Steric number = 4 ( sp ^3 ). Geometry is bent. For I ₃⁻ : Central atom I has 7 valence electrons + 1 (charge) = 8. It forms 2 bonds and
