Q23 / 118 · NTA Abhyas (JEE Main) 2020 · Chemistry · Coordination Compounds

Crystal field stabilization energy for high spin $d^{4}$ octahedral complex is

Correct answer
A
$- 0.6 Δ_{0}$
B
$- 1.8 Δ_{0}$
C
$- 1.6 Δ_{0} + P$
D
$- 1.2 Δ_{0}$

Solution

For high spin

d^{4}

Octahedral complex the splitting is given by

CFSE = [- 0 .4 - × 3 + 0 .6 × 1] Δ_{0}

= [- 1.2 + 0.6] Δ_{0}

= - 0.6 Δ_{0}

Hence, the correct answer is option: 'A'.
