Question

For `d^(4) ` ions the fourth electron enters one of the ` e_(g ) ` orbitals giving rise to the configuration ` t_(2g)^(3) e_(g) ^(1)` , when
A. `Delta _(0) gt P`
B. `Delta _(0) lt P`
C. ` Delta_(0)=P`
D. `Delta _(0) gt P`

Answer 1

Correct Answer - B
The fourth electron enters one of the `e_(g) ` orbitals giving rise to the configuration `t_(2g)^(3)e_(g)^(1)` when `Delta _(0) lt P` pairing does not occur
