 ${\mathrm{d}}_{{\mathrm{x}}^2-{\mathrm{y}}^2}$ atomic orbital                                    $—$One nodal plane 

 $P_y$ atomic orbital                                          $—$Two nodal plane

Both X' atoms occupy axial positions which are formed by overlapping of p and d-orbitals only

All $\mathrm{M}—\mathrm{X} \mathrm{bond} \mathrm{lengths} \mathrm{are} \mathrm{identical} \mathrm{in} \mathrm{both} {\mathrm{MX}}_4 \mathrm{and} {\mathrm{MX}}_4\mathrm{X}{\text{'}}_2 \mathrm{compounds}$

Central atom 'M' does not use anyone valence non-axial set of d-orbital in hybridization of final product

Hybridization of central atom 'M' remains same in both reactant and final product.
