What is the name of the compound represented by CuCl2?

The compound represented by CuCl2 is known as Copper (II) chloride. In this formula, copper (Cu) has an oxidation state of +2, which distinguishes it from Copper (I) chloride, where copper would have an oxidation state of +1. The Roman numeral II in the name indicates this oxidation state. The presence of two chlorine (Cl) atoms, each with a -1 charge, balances the +2 charge of the copper ion, leading to the formula CuCl2.

Copper (III) chloride would imply an oxidation state of +3 for copper, which is not represented by this formula, making it an incorrect option. Just "Copper chloride" lacks the specificity about the oxidation state and would be deemed too vague in chemical nomenclature, as copper can exist in multiple oxidation states.
