Question

The number of geometrical isomers found in the metal complexes , ,  and  respectively, are:

Canvas Classes · Accepted Answer

Strategy:
 Evaluate the isomerism count based on geometry formulas: square planar , tetrahedral , octahedral , and octahedral .

Step 1: Evaluate each complex separately
- : Square planar (). Exists as cis and trans isomers. (Count = 2).
- : Tetrahedral (). All positions are equivalent and equidistant. No geometrical isomerism possible. (Count = 0).
- : Octahedral (). Exists as facial (fac) and meridional (mer) isomers. (Count = 2).
- : Octahedral (). Exists as cis and trans isomers. (Count = 2)
