How many stereoisomers are there for the square planar compound Pt(NH₃)₂Cl₂, which is a potent anticancer agent? A)0 B)1 C)2 D)3 E)4

Question

Quizplus · Accepted Answer

Square planar complexes, such as the one described for the Pt compound, can exhibit geometrical isomerism. However, due to the specific arrangement of ligands around the platinum center, this compound can exist as two distinct geometrical isomers: the cis and trans forms. These isomers arise from the different possible arrangements of the ligands (in this case, NHS, Cl, and two others) around the central metal atom. Optical isomerism is not possible in square planar complexes, limiting the total number of stereoisomers to 2.
