Question

Name of the complex compound [Co(NH3)4(H2O)Br](NO3)2

Answer 1

Answer:

Tetraaminebromoaquacobalt(1) nitrate, since we have to write the name of the compound in alphabetical order.

Answer 2

Tetraamminebromidoaquacobalt(ll)nitrate

Explanation:using iupac rules

1.Assigning charge the metal here complex is cationic ,,[Co(NH3)4(H2O)Br]+ so Co(||)

2.Ligands are named in preference to metal ion in the coordination sphere Tetraa*mmine, a*qua, b*romido then cobalt (ll)

Arrange them in alphabetical order Tetraammineaquabromidocobalt(ll)

3.Add the name of the ionisable valency ...here nitrate

Hence Tetraammineaquabromidocobalt(ll)nitrate

Remember that name should be written continuously without any space
