MCQ
Complex species that exhibits isomerism is:
  • A
    [Ag(NH3​)2​]+
  • B
    [Co(NO2​)(NH3​)5​]2+
  • C
    [PtCl2​(en)]
  • D
    [CoCl(NH3​)5​]2+
✓

Answer

  1. [Co(NO2​)(NH3​)5​]2+

Explanation:

None of the given complexes can exhibit either geometrical or optical isomerism. But the complex [Co(NO2​)(NH3​)5​]2+ shows linkage isomerism as it contains nitro group which is ambidentate ligand and can be attached through either N atom or O atom.
