# Lewis Structure of SO2 [duplicate]

What is the structure of SO2? I have seen two different ways the Lewis Structure is written:

The formal charges of the SO2 with the single bond and a double bond is larger than the SO2 with two double bonds. So I would assume that the one with two double bonds is the correct structure. But chemistry books I have looked at (Zumdahl Edition 5 and 7) says that it is the opposite.

Which is the correct Lewis Structure?

• @Hawkeye check out molecular orbital theory. You can easily hold sulfur hexafluoride together without using "outer $d$ orbitals". Dec 8 '17 at 23:41
