Answer & Solution
Correct Answer
(A) A - Q B - S C - P D - R
Step-by-step Solution
Detailed explanation
\([\text{Pt}(\text{NH}_3)_2\text{Cl}_2]\) is a square planar complex of the type \(MA_2B_2\). It exhibits cis-trans isomerism. This matches Q. \([\text{Ni}(\text{NH}_3)_2\text{Cl}_2]\) is a tetrahedral complex of the type \(MA_2B_2\) since \(\text{Ni}^{2+}\) is a \(3d^8\) ion…
