7th Edition 2D.7

Are the bond lengths of SO2 and SO3 the same?
Does the lone pair on SO2 affect bond length at all?

The lone pair of SO2 does affect the bond lengths of the molecule. When there is a lone pair, the electrons of that pair repel the electrons in the atomics in the molecule, and thus push the atoms further than they would be without a lone pair present. Thus, the bond lengths of SO2 are slightly longer than that of SO3.
