5. Circle the compounds below that are aromatic.
5. Circle the compounds below that are aromatic. Aromatic compounds obey Huckel's rule: they have 4n+2 Tt-electrons (where n = any integer including zero) in a closed, contiguous Tt-system (see pg 760, 764-766). Remember delocalized lone pairs are part of the T-system whereas localized lone pairs are not (see pg 765-768). Empty p-orbitals can also be part of the it-system.
