hydrogen sulfite ion, HSO3-

Postby Imelda Mena 3I » Mon Nov 26, 2018 6:11 pm

Hi! Homework problem 3.57b from the 6th edition asks for the Lewis structure of hydrogen sulfite ion and I got a different answer than the one on the answer key. Can someone explain how they got the H attached to O and not S (the central atom)? I got a tetrahedral shape, with S as the central atom and the three O and H attached to S through single bonds. Then I have all three O with 6 lone pairs. Why can this not be one of the Lewis structure for hydrogen sulfite ion? Thank you!

The structure given in the answer key is favorable because of formal charge.

Oh okay thank you! So the structure that I described above is still one possible structure but it is less stable?
