- D A, B, C, D & E
Answer & Solution
Correct Answer
(B) A, B & D only
Step-by-step Solution
Detailed explanation
(A) \( Co^{3+}:-3d^{6} \), \( NH_{3} \Rightarrow S.F.L \) Hybridisation \( \Rightarrow d^{2}sp^{3} \), Inner orbital complex. (B) \( Mn^{3+}:-3d^{4} \), \( Cl^{-} \Rightarrow W.F.L\) Hybridisation \( \Rightarrow sp^{3}d^{2} \), Outer orbital complex. (C) \( Co^{3+}:-3d^{6} \),…
