Which complex compound is the most stable?

  1. A.[Co(NH3)3(H2O)2Br](NO3)2\mathrm{[Co(NH_3)_3(H_2O)_2Br](NO_3)_2}
  2. B.[Co(NH3)3(NO3)3]\mathrm{[Co(NH_3)_3(NO_3)_3]}
  3. C.[CoCl2(en)2]NO3\mathrm{[CoCl_2(en)_2]NO_3}✓
  4. D.[Co(NH3)6]2(SO4)3\mathrm{[Co(NH_3)_6]_2(SO_4)_3}

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
