Aromaticity Worksheet CHEM 2410 Fall 2019 Determine if the following compounds are aromatic, anti-aromatic or non-aromatic. Give reasons for your answer. ***Assume all the cyclic compounds are planar (flat) for these problems. Summary Notes: Aromatic - 4n+2 pi electrons, complete cyclic conjugated pi system and planar (flat) Anti-aromatic - 4n pi electrons, cyclic conjugated pi system and planar(flat) Non-aromatic-breaks any of the above rules (all other compounds) Sp3 hybridized heteroatoms (O, S, N) are involved in the pi system Sp2...

please answer!
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.) 1. A.Electrons in a cyclic conjugated system. B.The compound is (a,...
