What is the shape of the molecules which have sp3d hybridization?
Trigonal bipyramidal
We know that
1s + 1p → 2 sp hybrid orbitals
1s + 2p → 3 sp2 hybrid orbitals
1s + 3p → 4 sp3 hybrid orbitals
1s + 1p + 1d → 5 sp3d hybrid orbitals
So, we have to arrange 5 sp3d hybrid orbitals around the central atom, such that the molecule experiences least electrostatic repulsion.
It comes out to be Trigonal Bipyramidal
