Can anyone explain SO2 to me
« on: April 07, 2009, 09:31:46 AM »
Can anyone explain to me how SO2 is stable? I keep trying to draw its lewis chart and balance its octet but I can't seem to get it right.

Oxygen wants 2 and Sulfur wants 2.

O=S=O seems wrong because Sulfur wants 2 and actually gets 4 which would be bad.

 So I wound up trying to draw a circle where oxygen binds to oxygen and the sulfur binds to them both but somehow that doesn't seem right. Can anyone explain this?
Thanks

For the very common, simple molecules you're working with, you should check out the relevant wikipedia page, they talk quite a bit about structure, and you'll pick up the basics.  http://en.wikipedia.org/wiki/Sulfur_dioxide
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

Though you may want to look up the EXCEPTIONS to the octet rule, typically those w.r.t. elements in period 3 onwards.

Sulfur is actually capable of forming six bonds.  It is one of those dirty little tricks the molecular world pulls on us.
