The “extra” polarity associated with the second resonance structure would contribute to the molecular structure but would not be accounted for by standard group dipoles.c. There are three major factors contributing to the overall dipole moments: (I) the ơ-bond dipo Solutions manual for part a le associated with the C-0 and C—N bonds; (2) the IT-bond dipole associated with delocalization of TĨ electrons from the heteroatom to the ring; and (Solutions manual for part a
3) the dipole moment associated with the unshared electron pair (for O) or N—H bond (for N). All these factors have a greater moment toward rather thaSolutions to ProblemsChapter 11.1, a.
