Question

which of the following is the correct electronic configuration in octahedral complex with d_4 configuration?

Answer 1

Answer:

option 4

Explanation:

Answer 2

we have to find the electronic configuration of octahedral complex with d⁴ configuration.

solution : we know ∆₀ is the crystal field splitting energy and P is electron pairing energy

here if ∆₀ > P means, strong field ligands i.e., electrons are paired

then, configuration of d⁴ must be t_2g⁴ e_g⁰

and if ∆₀ < 0 it means, weak field ligands i.e., electrons are unpaired

then configuration of d⁴ must be t_2g³ e_g¹

here only option (4) t_2g³ e_g¹ , ∆₀ < P is correct statement.
