Your friend tried to determine the name of the ionic compound CuClO2 using the IUPAC naming rules we learned. They believe the answer is copper chlorate. Explain why their answer is incorrect.

Their answer is incorrect because CIO2 is not chlorate. ClO3 is chlorate. ClO2 is chlorite however.  Furthermore, it is not copper chlorite.  It is copper(I) chlorite because copper or Cu is a transition metal and a transition metal requires a roman numeral. They require a roman numeral because a transition metal doesn't have a specific charge/oxidation number as a cation. A transition metal can have like either a charge of +1, +2, +3, +4. Therefore, the correct answer is Copper(I) Chlorite.
