        Isomerism which arises due to the presence of two different atoms in the same ligand is called

    A)  linkage                                

    B)  hydrate

    C)  salt                                       

    D)  Both (a) and (b)

    Correct Answer: D

    Solution :

                    When two different donor atoms are present in l the same ligand that may thus attach through either of the two atoms, then this type of isomerism is called linkage, structural or salt isomerism Example: The best example is nitrite ion \[(NO_{2}^{-})\]which may attach to the metal ion either trough the nitrogen atom to act as a nitro ligand\[(-N{{O}_{2}})\]or through one of the oxygen to act as a nitrito ligand\[(-ONO)\].
