Which one of the following normally acts as a bidentate ligand in complexes with transition metal ions?

Question

Quizplus · Accepted Answer

Ethylene diamine is a bidentate ligand as it has two nitrogen atoms that can donate a pair of electrons to the metal center, forming two coordinate bonds. In contrast, options A, B, and C are monodentate ligands, meaning they can only donate one pair of electrons to the metal center. Option E is a polydentate ligand, but it has more than two coordinating atoms, making it a multidentate ligand.
