Select ligand which is bidentate and can form chelates:
Correct answer: D. CH2(NH2)CH2(NH2)
- A. CH3 NH2
- B. PH3
- C. H2O
- D. CH2(NH2)CH2(NH2)
Explanation
Ethylene diamine is a bidentate ligand as it has two Nitrogens, each containing a lone pair of electrons that they can donate to form two dative bonds with one central metal atom. A, B, and C all have only one lone pair of electrons thus they are monodentate ligands.

About VSEPR Theory
Valence shell electron pair repulsion theory predicts molecular shape by arranging bonding pairs and lone pairs around a central atom to minimize repulsion. Questions cover linear, trigonal planar, tetrahedral, trigonal bipyramidal and octahedral electron geometries, bond angles and distortions caused by lone pairs. Electron geometry is not always the same as molecular shape.
