Solutions to Selected Problems

In questions involving drawing resonance contributors, assume that all second-row atoms should have a complete octet in all structures with the exception of positively-charged carbons. P2.1: For each of the bonds indicated by arrows b-f in the figures below, describe the bonding picture. An example is given for bond 'a'. Note that for a double bond (bond 'c'), you will need to describe two bonds. Note: you are being asked to describe the bonding picture for one specific resonance contributor. Example answer for bond a: "this is a sigma bond formed by the overlap of an sp3 orbital on one carbon and an sp2 orbital on another carbon."
