9.32     What will be the correct order for the wavelengths of absorption in the visible region for the following:

                 [Ni(NO_{2})_{6}]^{4-}, [Ni(NH_{3})_{6}]^{2+}, [Ni(H_{2}O)_{6}]^{2+} ?

The order of the wavelength of absorption will be decided from the order of their CFSE values.

The CFSE values increase in the order :-            H2O < NH3 < NO2 - 

Hence, the order of wavelengths of absorption in the visible region is    :              [Ni(H2O)6]2+ > [Ni(NH3)6]2+ > [Ni(NO2)6]4-
