The splitting diagram for square planar complexes is more complex than for octahedral and tetrahedral complexes and is shown below with the relative energies of each orbital.

Which of the following set of `de^(-)` have same crystal field stabilisation energy value for tetrahedral complex neglecting pairing energy (P) :
`(P) d^(1), d^(6)" "(Q) d^(2), d^(7)`
`(R ) d^(3), d^(8)" "(S) d^(4), d^(9)`
`(T) d^(5), d^(10)`

Options

A. Only T
B. Q, R and T
C. P, Q and S
D. P, Q, R, S and T

Answer

D

Explanation

`d^(2) to 2xx6"Dqt"`
`d^(3) to 2xx6-1xx4" Dqt"`
`d^(4) to 2xx6-2xx4" Dqt"`
`d^(5) to 2xx6-3xx4" Dqt"`
`d^(6) to 3xx6-3xx4" Dqt"`
