Question:
A group of atoms can function as a ligand only when
A group of atoms can function as a ligand only when
Updated On: Apr 2, 2024
- It is a small molecule
- It is capable of acting as donor of electron pair
- It is a negatively charged ion
- It is positively charged ion
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The donor atoms molecules or anions which donate a pair of electrons to the central metal atom or ion and form a coordinate bond with it are calied ligands. Ligands are electron pair donors so they are Lewis bases.

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
