JEE MainChemistryCoordination CompoundsMCQ+4 / −1
Three complexes, [CoCl(NH3)5]2+[CoCl(NH_3)_5]^{2+}[CoCl(NH3​)5​]2+(I), [Co(NH3)5H2O]3+[Co(NH_3)_5H_2O]^{3+}[Co(NH3​)5​H2​O]3+ (II) and [Co(NH3)6]3+[Co(NH_3)_6]^{3+}[Co(NH3​)6​]3+(III) absorb light in the visible region. The correct order of the wavelength of light absorbed by them is :
  1. A
    (III) > (I) > (II)
  2. B
    (III) > (II) > (I)
  3. C
