B) The CO₃^2- ion contains two C-O single bonds and one C O double bond. C) The CO₃^2- ion contains three C-O double bonds. D) The CO₃^2- ion contains two C-O single bonds and one C O triple bond. E) None of the above is true.

Question

Quizplus · Accepted Answer

According to the Lewis structure, there is one C-O single bond and one C-O double bond in the CO₃^2- ion. The double bond can delocalize onto the sulfur atom to form a resonance structure with two C-O single bonds, but that does not change the fact that there is only one C-O double bond in the compound. Therefore, choice B is the correct answer. The other choices either have too many or too few C-O bonds compared to the actual compound.
