Question

Quizplus · Accepted Answer

For a square planar complex of the formula [MXaYbZcWd], where M is the metal and X, Y, Z, W are different ligands, the number of geometric isomers possible is determined by the arrangement of the ligands around the central metal atom. In this case, with four different ligands (N, Br, Cl, and S), there is only one way to arrange them in a square planar geometry to create distinct isomers, which results in 2 geometric isomers. These isomers differ based on the positions of the ligands relative to each other (e.g., trans and cis configurations).
