A group of atoms can function as a ligand only when
- A it is a small molecule
- B it has an unshared electron pair
- C it is a negatively charged ion
- D it is a positively charge ion
Answer & Solution
Correct Answer
(B) it has an unshared electron pair
Step-by-step Solution
Detailed 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 called ligands. Ligands are electron pair donors so they are Lewis bases.
