Q. The complex [Pt(Py)(NH₃)BrCl] will have how many geometrical isomers?
A) 2
B) 3
C) 4
D) 0
Explanation
[Solution from source] [Pt(py)(NH₃)BrCl] is square planar of type [Mabcd]. Fixing one ligand, any of the other three can be trans to it, giving 3 geometrical isomers. Two isomers is the answer only for [Ma₂b₂]-type complexes. Answer (2).
