Assertion : Linkage isomerism arises in coordination compounds containing ambidentate ligand.

Reason: Ambidentate ligand has two different donor atoms.

  • If both assertion and reason are true and reason is the correct explanation of assertion.

  • If both assertion and reason are true but reason is not the correct explanation of assertion.

  • If assertion is true but reason is false.

  • If both assertion and reason are false.


A.

If both assertion and reason are true and reason is the correct explanation of assertion.

Ligand which can ligate through two different atoms is called ambidentate ligand. Examples of such ligands are the NO2– and SCN ions. NO2– ion can coordinate either through nitrogen or through oxygen to a central metal atom/ion.
