Question

Complex compounds are molecular compounds which retain their identities even when dissolved in water. They do not give all the simple ions in solution but instead furnish complex ions. The complex compounds are often called coordination compounds because certain groups called ligands are attached to the central metal ion by coordinate or dative bonds. Coordination compounds exhibit isomerism, both structural and stereoisomerism. The structure, magnetic property, colour and electrical properties of complexes are explained are explained by various theories Generally, a group of atoms can function as a ligand if (A) They are free radicals (B) They are either neutral molecules or negatively charged ions (C) They are positively charged ions (D) None of the above

Ligand must have capacity to donate lone pair of electrons to form coordinate bond
