Which complex ion shape is not capable of showing cis-trans isomerism?
A)octahedral
B)square planar
C)tetrahedral
D)two of these
E)none of these

Question

Quizplus · Accepted Answer

Tetrahedral complexes have four ligands attached to the central metal ion and cannot have cis-trans isomerism because the placement of the ligands with respect to each other is fixed in any orientation. On the other hand, octahedral and square planar complexes can have cis-trans isomerism because there are two different ways the ligands can be arranged around the central metal ion.
