Question

Ligands which can form two coordinate bonds from
each ion or molecule to the transition metal ion are?​

Answer 1

Answer:

Bidentate ligands – Ligands that can donate two pairs of electrons to the central metal ion to form two coordinate bonds.

Answer 2

Polydentate ligands- Bidentate ligands

Explanation:

• Lewis bases which donate two pairs ("bi") of electrons to a metal atom is termed as Bidentate ligands.
• Bidentate ligands are said to as chelating ligands because they can "grab" a metal atom in two different places.
• Chelate could a complex that contains a chelating ligands.
• for example- Ethylene diamine could be a neutral molecule that contains two Nitrogen atoms which will each donate a pair of electrons to a metal atom.
• Common samples of bidentate ligands are ethylenediamine (en), the oxalate ion (ox), EDTA etc
