According to the polygon rule, cyclooctatetraene (assumed planar) has 8 π electrons. Which statement about its MO filling is correct ?
Options:
Answer:
A
Solution:
The polygon rule gives 1 + 2 + 2 + 2 + 1 MOs. 8 electrons fill the one lowest MO (2) and the two bonding MOs (4), leaving 2 electrons for the two degenerate non-bonding MOs. By Hund's rule they go one in each (unpaired), which makes the planar form unstable (anti-aromatic).
