Question

Consider the following compounds with their regular geometries.
A: Square planar
B: Trigonal bipyramidal
C: Square pyramidal
D: Octahedral
E: Pentagonal bipyramidal
Calculate value of $(x+y-z)^2$, where x is total number of axial d-orbitals having zero nodal plane, y and z are total no. of non-axial and axial d-orbitals respectively each one having two nodal planes used in hybridization of central atoms of compounds A to E.

Correct answer: **ANSWER: 0**<BR>SOLUTION: THE HYBRIDIZATIONS ARE A ($DSP^2$, USING $D_{X^2-Y^2}$), B ($SP^3D$, USING $D_{Z^2}$), C ($SP^3D$, USING $D_{X^2-Y^2}$), D ($SP^3D^2$, USING $D_{X^2-Y^2}, D_{Z^2}$), E ($SP^3D^3$, USING $D_{X^2-Y^2}, D_{XY}$). BASED ON THE NUMBER OF NODAL PLANES: $X = D_{Z^2} = 3$, $Y = D_{XY} = 1$, $Z = D_{X^2-Y^2} = 4$. THEREFORE, $(X+Y-Z)^2 = (3+1-4)^2 = 0$.
