Solution

The correct option is D $[C r {{(N H}_{3})}_{5} B r] S O_{4}$
The compound which has the same composition but gives different ions in solution shows ionization. So, $[C o (N H_{3})_{5} B r] S O_{4}$ is ionization isomer.

$[C o (N H_{3})_{5} B r] S O_{4} ⇋ [C o (N H_{3})_{5} B r]^{2 +} + S O_{4}^{2 -}$

$[C o (N H_{3})_{5} S O_{4}] B r ⇋ [C o (N H_{3}) S O_{4}]^{+} + B r^{-}$ .

The correct option is D [Cr(NH3)5Br]SO4The compound which has the same composition but gives different ions in solution shows ionization. So, [Co(NH3)5Br]SO4 is ionization isomer.[Co(NH3)5Br]SO4⇋[Co(NH3)5Br]2++SO2−4[Co(NH3)5SO4]Br⇋[Co(NH3)SO4]++Br−.
