- D \(B\) and \(C\)
Answer & Solution
Correct Answer
(B) \(A, B\) and \(D\)
Step-by-step Solution
Detailed explanation
\(\left[ NiBr _2 Cl _2\right]^{2-} \rightarrow\) This complex species is tetrahedral as \(Br ^{\Theta}\) and \(Cl ^{\Theta}\) are weak field ligands. \(\left[ PtBr _2 Cl _2\right]^{2-} \rightarrow As\) Pt belongs to 5 d series. This complex species is square planar. Both the…
