For a d 4 metal ion in an octahedral field, the correct electronic configuration is :
Options
- At 2 g 3   e g 1 when ∆ O < P
- Bt 2 g 3   e g 1 when ∆ O > P
- Ct 2 g 4   e g 0 when ∆ O < P
- De g 2   t 2 g 2 when ∆ O < P
Correct answer
A. t 2 g 3   e g 1 when ∆ O < P
Step-by-step solution
For d 4 configuration if Δ 0 < P the electronic configuration is t 2 g 3 ,   e g 1 .
