Question

Crystal field splitting energey `(CFSE)` for the complex `[Cr(NH_(3)_(6)]^(2+)` is when `P =125` and `Delta_(0)=250kJ mo1^(-1)` .
A. `d^(5)`
B. `d^(6)`
C. `d^(8)`
D. `d^(10)`

Answer 1

Correct Answer - a
`DeltaltP` weak field no pairing octahedral
Structure of `d^(5) = (t_(2g)^`3`e_(g)2) = - 0.4 xx 3 + 2 xx 0.6 =0` .
