Terminology:
common names: toluene, cumene, styrene, phenol, aniline, anisole
benzoic acid, benzaldehyde
annulene, naphthalene, anthracene, phenanthrene
pyridine, pyrrole, furan, thiophene, pyrimidine, imidazole
group names: phenyl, benzyl
position names: ortho, meta, para, benzylic
aromaticity, Huckel's Rule
recognize aromaticity as special stability, with various implications, such as
show low reactivity compared to alkenes
do not undergo addition reactions like alkenes
show NMR ring current effects
recognize the special stability of intermediates at a benzylic
position, based on resonance delocalization
predict the expected patterns of MOs for various conjugated pi systems
write mechanisms for reactions at benzylic positions
write resonance forms for benzylic intermediates
predict whether a given compound is aromatic, antiaromatic, or nonaromatic
