Quizplus · Accepted Answer

Structures 3 and 4 are square planar which allows for geometric isomerism to occur. Therefore, the correct statement is that 3 and 4 are geometric isomers. Structures 1 and 2 are octahedral and cannot exhibit geometric isomerism. They could potentially be optical isomers if they had chiral ligands, but there is no information given about the ligands. Structural isomers have different connectivity between atoms, which is not observed in structures 1-4. Therefore, the correct answer is E) 3 and 4 are geometric isomers.
