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.) CH3 1. A.Electrons in a cyclic conjugated system. B.The compound is (a, aa, or na) 2.

• You do not have to consider stereochemistry.
• In the case of a missing reactant, there may be more than one answer. If so, draw all possible
reactants,
• Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom
right corner.
Separate multiple reactants using the + sign from the drop-down menu.
