Determine the number of electrons in a system of cyclic conjugation (0 if no cyclic conjugation) Specify whether the species is a- aromatic, aa- antiaromatic, or na- nonaromatic.

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.) 1. A.Electrons in a cyclic conjugated system. B.The compound is (a, aa, or na) s 2. .
