Choose the correct statement about isomers of [Pt(H₂O)₂(NH₃)Cl]Br. A) I is cis, II is trans. B) The two molecules are the same. C) The two molecules are the same but one is turned over. D) They are not isomers. E) I is trans, II is cis.

Question

Quizplus · Accepted Answer

The complex contains two bidentate ligands, H₂O and NH₃, which can bind to the central Pt ion in either a cis or trans configuration. Therefore, the two isomers are possible, one with the ligands in a cis configuration (I) and one with the ligands in a trans configuration (II). The prefix "cis" means that the ligands are positioned adjacent to each other across one face of the metal ion, while the prefix "trans" means that the ligands are on opposite faces of the metal ion, separated by the Cl ligand. Thus, choice E is the correct answer, stating that I is trans and II is cis.
