The complex [Zn(NH3)2Cl2]^2+ does not exhibit cis-trans isomerism. The geometry of this complex must be .A) trigonal bipyramidalB) tetrahedralC) octahedralD) square planarE) either tetrahedral or square planar

B) tetrahedral

Explanation:

From the information:

The given complex is . In this complex, the number of ligands attached to the central metal atom Zn is 4. This, in turn, affects the coordination number of the complex to be 4. For a coordination number with 4, the likely geometry can either be tetrahedral or square planar, and cis-trans isomerism only occurs in a square planar geometry.

But, from the question, we are informed that the complex does not exhibit cis-trans isomerism, therefore the complex must be tetrahedral.
