Answer:
B) tetrahedral
Explanation:
From the information:
The given complex is [tex]\Big [Zn (NH_3)_2Cl_2 \Big ]^{2+}[/tex]. 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.
