Note: In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.
Assertion: Linkage isomerism arises in coordination compounds containing ambidentate ligand.
Reason: Ambidentate ligand has two different donor atoms.
Assertion and reason both true, the reason is the correct explanation of assertion. Ambidentate ligands are those which have two different donor atoms in one single ligand. And these types of ligands give rise to the formation of linkage isomerism where the isomers only differ in the linkage of the ligand atom to the central metal atom.
Eg- this can be observed in the case of [Co(NH3)5(NO2)]Cl2 complex.
• In one form, the complex appears red in which the nitrite ligand is bound through one of the oxygen atom (-ONO) to the Co atom.
• In the other form, the complex is obtained in the yellow form in which the nitrite ligand is bound through the nitrogen atom (-NO2).
