Why is the arrangement of SO2 the way that it is?
Why don't both Oxygens double bond to Sulfur? Why does only one Oxygen double bond? Why does S have a lone pair?
Doesn't Oxygen like to double bond? Why don't both Oxygens double bond to S?

0=S=0 bent

Review your lewis dot structure rules. As you can see S and O have 6 valence electrons. So there are a total of 18 electrons.

Following the octet rules and the Vsepr model you should get the bent structure depicted above.

S can have 2 double bonds and a lone pair of electrons at the same time. S does not have to go by the octet rule since it has open d orbitals.

Fellow [Any Field]
this is true... but draw out the orbitals... how would you have an atom with two pi bonds and it not be linear....
