Question

The total number of possible isomers for square-planar \( \text{[Pt(Cl)(NO}_2)(NO_3)(SCN)]^{2-} \) is:

• A. 16
• B. 12
• C. 8
• D. 24

Hint:

Isomerism in coordination compounds is determined by the positions of ligands and their ability to form different spatial arrangements.

Answer 1

The Correct Option is B

For square-planar coordination complexes, the number of possible isomers depends on the ligands and their positions. For the given complex, we find that there are 12 possible isomers.

Step 2: Conclusion.
Thus, the correct answer is 12.
