2 2 Resonance ± sometimes more than one Lewis structure is possible for a given molecule or polyatomic ion (i.e. two or more equivalent Lewis structures - Lewis structures containthesamenumbers of singleand multiple bonds) ± e.g. SO 2 ± two possible “resonance” structures for SO 2 ± based on either of the structures above, there should be O SO OSO 3 two types of S-O bonds in the molecule: ± one shorter bond (i.e. the double bond) ± one longer bond (i.e. the single bond) ± note the double bond would be “stronger” than the single bond Resonance (cont’d) ± experiments show that in SO 2 the S-O bonds are equivalent (i.e. the S-O bond distance is the same for both S-O bonds) with a length and strength between that ofasingleand double bond ± with that knowledge, are either of the resonance
