Question

The correct name of the compound $\left[Cu\right(N{H}_3{)}_4\left]\right(N{O}_3{)}_2$ according to IUPAC system is:

• A. cuprammonium nitrate
• B. tetrammine copper(II) dinitrate
• C. tetrammine copper(II) nitrate
• D. tetrammine copper(III) dinitrate

Answer 1

The correct option is B tetrammine copper(II) dinitrate

As $N{O}_3$ has $-1$ charge & $N{H}_3$ is a neutral ligand ,so copper has +2 oxidation state.

Thus, IUPAC name of compound $\left[Cu\right(N{H}_3{)}_4\left]\right(N{O}_3{)}_2$ is Tetrammine copper (II) dinitrate.

Therefore, the correct option is $B$.
