	1. These are polyatomic ions, not compounds, so the title should be changed. 2. I have always seen thiocyanate written SCN-, so at least give an alternate spelling option. 3. The "l" in "Cl" shouldn't be capitalized - you capitalized it in hypochlorite and chlorate. Other than that, great idea for a quiz!

	A second to SecretAZNMan, with one addition: for acetate, CH3COO and C2H3OO should also be accepted.

	I've seen acetate written CH2COOH often as well.

	A better mercury ion for this quiz would be mercury (I), Hg2 2+, since Hg 2+ is not polyatomic.

	I agree with the mercury comment, but I have to say that CH2COOH suggests a negative charge on the methyl C, which is not the case; the negative charge is on O.
