Question

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 hybridized heteroatoms are NOT involved in the pi system Add in missing double bonds as needed to help you answer the question Compound Complete cyclic, Number of pi Aromatic, conjugated pi electrons? antiaromatic or system? Yes or nonaromatic? No Antiaromatic Yes bero
