1.	The complex ions [Co(NH3)5(NO2)]2+ and [Co(NH3)5 (ONO)]2+ are called (a) Ionization isomers (b) Linkage isomers (c) Co-ordination isomers (d) Geometrical isomers
Answer» LINKAGE isomers Explanation:The isomerism which arises due to AMBIDENTATE ligend is called linkage isomers.Here, a ligend binds through two different sites.For EXAMPLE :- in the given question, NO2 in first case binds through N ( called NITRITO- N) while in the second case bind through O (called nitrito-O).
