  1. A
    −125Δo+P{{ - 12} \over 5}{\Delta _o} + P5−12​Δo​+P
  2. B
    −125Δo+3P{{ - 12} \over 5}{\Delta _o} + 3P5−12​Δo​+3P
  3. C
    −25Δo+2P{{ - 2} \over 5}{\Delta _o} + 2P5−2​Δo​+2P
  4. D
    −25Δo+P{{ - 2} \over 5}{\Delta _o} + P5−2​Δo​+P

Correct answer: B

For low spin d6 complex electronic configuration

= t2g6eg0t_{2g}^6e_g^0t2g6​eg0​

∴\therefore∴ x = 6, y = 0, z = 3

C.F.S.E. = (– 0.4 × 6 + 0 × 0.6)Δ\Delta Δ0 + 3P

= −125Δ0+3P - {{12} \over 5}{\Delta _0} + 3P−512​Δ0​+3P
