Solution
The correct option is C B in BF3 In BF3, the ground state electronic configuration of Boron is 1s22s22Px1. excited state electronic configuration
is 1s22s12Px12Py1
One electron from one ′s′ orbital and two electrons from ′p′ orbital overlaps with ′p′ orbital electrons of Flourine to form three sp2 hybridised bonds. So, BF3 has sp2 hybridisation.
Flourine (a)
But in H3O+,NH3 and PCl3, the hybridisation involves one electron from ′s′ orbital, 3 electrons for ′p′ orbitals in central orbital forming sp3 hybridisation.
