How many of the following compounds exhibit geometric isomers? I.Pt(NH₃)₂Cl₂ (square planar) II.[Co(H₂O)₂]Cl₃ III.Ni(NH₃)₄(NO₂)₂ IV.K₂[CoCl₄] A)0 B)1 C)2 D)3 E)4

Quizplus · Accepted Answer

I and IV do not have any double bonds or chiral centers, so they cannot exhibit geometric isomers. II has a chiral center (the Co atom), but the ligands attached to it are all the same, so there are no geometric isomers. III has a double bond, which means it can exhibit geometric isomers. Therefore, only compounds II and III exhibit the possibility of geometric isomers.
