### Identifying Aromatic Compounds Organic Chemistry

Identify Aromatic Antiaromatic or Nonaromatic Compounds. Cyclic congugation increases the number of p orbital interactions in the conjugated system, stabilizing the pi bonds. Cyclohexene lacks this stability, and the energy of its pi bond is greater (less stable)., MГ¶bius aromaticity occurs when a cyclic system of molecular orbitals, formed from p ПЂ atomic orbitals and populated in a closed shell by 4n (n is an integer) electrons, is given a single half-twist to form a MГ¶bius strip.A ПЂ system with 4n electrons in a flat (non-twisted) ring would be antiaromatic, and therefore highly unstable, due to the symmetry of the combinations of p atomic orbitals..
