Organic Chemistry II know the 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, Frost Circle
recognize aromaticity as special stability, with various implications, such as
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 the resonance delocalization
predict the expected patterns of MOs for various cyclic pi systems
write acid-base reactions for phenols, including aqueous extraction procedures
write typical reactions for phenols
write mechanisms for reactions at benzylic positions
use benzylic ethers as protecting groups
predict whether a given compound is aromatic, antiaromatic, or nonaromatic
