Linkage Isomerism
Which pair represents linkage isomers?
Select the correct option:
Solution
[Co(NH3)5(NO2)]2+and[Co(NH3)5(ONO)]2+
Nitrite is an ambidentate ligand and can bind through N (nitro) or O (nitrito). Therefore [Co(NH3)5(NO2)]2+ and [Co(NH3)5(ONO)]2+ have the same composition but differ in donor atom attachment, making them linkage isomers.

Solution
Correct Answer:
[Co(NH3)5(NO2)]2+and[Co(NH3)5(ONO)]2+
Nitrite is an ambidentate ligand and can bind through N (nitro) or O (nitrito). Therefore [Co(NH3)5(NO2)]2+ and [Co(NH3)5(ONO)]2+ have the same composition but differ in donor atom attachment, making them linkage isomers.
