Question
All of the following are named correctly EXCEPTGroup of answer choices(a) NiCl2.6H2O ; nickel(II) chloride hexahydrate.(b) MnO2 ; manganese(IV) oxide.(c) TiCl4 ; titanium(IV) chloride.(d) CuI ; copper(II) iodide.(e) ZnSO4; zinc(II) sulfate.
Solution
The answer is (d) CuI ; copper(II) iodide.
Here's why:
(a) NiCl2.6H2O ; nickel(II) chloride hexahydrate. This is correct because NiCl2.6H2O is indeed nickel(II) chloride hexahydrate.
(b) MnO2 ; manganese(IV) oxide. This is correct because MnO2 is indeed manganese(IV) oxide.
(c) TiCl4 ; titanium(IV) chloride. This is correct because TiCl4 is indeed titanium(IV) chloride.
(d) CuI ; copper(II) iodide. This is incorrect because CuI is copper(I) iodide, not copper(II) iodide. The Roman numeral in the name indicates the charge of the metal ion. In this case, copper has a charge of +1, not +2.
(e) ZnSO4; zinc(II) sulfate. This is correct because ZnSO4 is indeed zinc(II) sulfate.
