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"-antiaromatic, or "na"-non-aromatic (neither aromatic nor antiaromatic). (Presume rings to be planar unless structure obviously prevents planarity. If there is more than one conjugated ring, count electrons in the largest.) 1. A. Electrons in a cyclic conjugated system. B. The compound is (a, aa, or na) 2. A. Electrons in a cyclic conjugated system. 0 B. The compound is (a, aa, or na) na For each of the species below, identify any cyclic conjugated system, then: A.
