For each of the species below, identify any cyclic conjugated
system, then:
A. Determine the number of electrons in a system
of cyclic conjugation (zero if no cyclic conjugation).
B. Specify whether the species is
"a"-aromatic, "aa"-anti-aromatic,
or "na"-non-aromatic (neither aromatic nor
anti-aromatic).
(Presume rings to be planar unless structure obviously prevents
planarity. If there is more than one conjugated ring, count
electrons in the largest.)
