How many resonance structures are required in the electron-dot structure of CO₃^2-? A)two B)three C)four D)five

Question

Quizplus · Accepted Answer

In the electron-dot structure of CO₃^2-, there are double bonds between the carbon and oxygen atoms, as well as between the sulfur and oxygen atoms. Therefore, resonance structures can be drawn to show the different electronic arrangements of these bonds. There are three possible resonance structures that can be drawn: 1) Double bond between carbon and sulfur, double bond between sulfur and oxygen 2) Double bond between carbon and oxygen, single bond between sulfur and oxygen 3) Double bond between sulfur and oxygen, single bond between carbon and oxygen Therefore, the best choice is B, which represents the three possible resonance structures of the electron-dot structure of CO₃^2-.
