Question

The correct name of $Pt(N{H}_3{)}_{4}C{l}_2|[PtC{l}_4]$

• A. tetrachloroplatinum(II) dichlorotetraamine platinate
• B. dichlorotetraammineplatinuin(IV) tetra chloroplatinate (II)
• C. tetraamminedichloroplatinum (IV ) tetrachloroplatinate (II)
• D. tetrachloroplatinum(II) tetraammine platinate(IV)

Answer 1

Answer: (C)

The name of the complex cation is written first followed by the name of the complex anion. The names of the ligands are written in the alphabetical order. The roman numerals IV and II ar written in parenthesis to indicate the oxidation state of platinum in complex cation and complex anion. The prefix tetra is used to indicate the number of amine and chloro ligands. Hence, the name of the complex $\left[Pt{\left(N{H}_3\right)}_{4}C{l}_2\right]\left[PtC{l}_4\right]$ is tetraamminedichloroplatinum(iv) tetrachloroplatinate(ii).
