Solution
The correct option is DNH+4 and NF3 Steric Number (x)=12(M+V−C+A). where, M = number of monovalent surrounding atoms V = number of valence electrons on the central atom C = charge (with sign) A=charge on anion For NO+2:H=12(5+0+0−1)=2 ∴sp hybridisation
For NO−3:H=12(5+0+1−0)=3 ∴sp2 hybridisation
For NH+4:H=12(5+4+0−1)=4 ∴sp3 hybridisation
NF3 Steric Number (x)=12(5+3−0+0). Steric Number (x)=4. Hybridisation =sp3
