Question, If you draw HSO3 ^1- Would the drawing have of it be 3 oxygens single bonded to the s with the S having 1 lone pair and the H being bonded to an oxygen, or would it be 2 oxygens single bond

ed to the S and one oxygen being double bonded to it with the S still having 1 lone pair and the H would be paired with one of the single bonded oxygens. I thought that it would be the last one that i mentioned but our exam review shows that it is the first answer that I stated and I dont know why

I need to know exactly how the question was formulated. See this picture attached though. enter image description here

Hey there Kris and Nika!

Nika, you are correct, the best structure of HSO3- would be the one that has less formal charges, and the one that has a negative charge on a more electronegative element, O, instead of S. Let us know if you have other questions Kris!

  • Kris the key is lacking other 2 resonance forms. I would ask professor or Ta for explanation. Good Luck! Nika commented 12 months ago
