Question

1. The complex, [Pt(Py)(NH3)BrCl] will have how many
geometrical isomers?
(a) 3 (b) 4 (c) 0 (d) 2 (2011)
give explanation
​

Answer 1

Answer:

It has three geometrical isomers. The complex is square planar and is of the type [M(abcd)]. It has three geometrical isomers. Explain on the basis of valence bond theory that [Ni(CN)4]2– ion with square planar is diamagnetic and the [NiCl4]2– ion with tetrahedral geometry is paramagnetic.
