QNEET-2013-Ch-1565: NEET 2013 Chemistry - Class 12 NEET-2013-Ch-1565 Solution: Crystal field splitting energy for high spin \(d^4\) octahedral …

Crystal field splitting energy for high spin d4d^4 octahedral complex is 1.2Δo1.2\Delta_o 0.6Δ00.6\Delta_0 0.8Δo0.8\Delta_o 1.6Δo1.6\Delta_o

Multiple Choice Options

  • A −- _ 1.2 Δ\Delta _ o
  • B −- _ 0.6 Δ\Delta _ 0
  • C −- _ 0.8 Δ\Delta _ o
  • D −- _ 1.6 Δ\Delta _ o

Step-by-Step Verified Solution

High spin d 4 = t 2g 3 e g 1 CFSE for octahedral complex = [� 0.4 (t 2g electrons) + 0.6 (e g electrons)] _ 0 = (� 0.4 _ 3 + 0.6 _ 1) _ 0 = (-1.2 + 0.6) _ 0 = -0.6 _ 0
