Web(13 points) (a).Use the polygon rule to draw an energy diagram for the MOs of a planar cyclooctatetraenyl system. (b).Fill in the eight pi electrons for cyclooctatetraene. Is … WebThe cyclooctatetraene has eight pi electrons. The Huckels rule predicts whether the annulene is aromatic or antiaromatic. If the number of pi electrons in the cyclic system is (4n+2), the system is aromatic and if it is 4n it is non-aromatic. Cyclooctatetraene us [8] annulene with eight pi electrons. So, it is 4n system with n=2.
Cyclooctatetraene is chlorinated to give a [4.2.0]- bicyclic compound, which reacts further with dimethyl acetylenedicarboxylate in a Diels-Alder reaction (DA). Retro-DA at 200 °C releases cis-dichlorocyclobutene.
