Question

A complex involving dsp2 hybridisation

Answer 1

In dsp2 hybridisation, orbitals involved are say, 3d and 4s(which have a very small energy difference) whereas in sp3 hybridisation, the orbitals involved are say,4s and 4d(which have a greater energy difference than that between 3d and 4s). Thus dsp2 hybridisation is favoured more.
