MCQ
The compounds $\left[\mathrm{Co}\left(\mathrm{SO}_4\right)\left(\mathrm{NH}_3\right)_5\right] \mathrm{Br}$ and $\left[\mathrm{Co}\left(\mathrm{SO}_4\right)\left(\mathrm{NH}_3\right)_5\right] \mathrm{Cl}$ represent:
  • A
    Linkage isomerism.
  • B
    Ionisation isomerism.
  • C
    Coordination isomerism.
  • No isomerism.

Answer
