Why Resonance is not possible in this structure ?
Answers
Answer:
Because of its bending, twisting, and non-planarity, cyclooctatetraene's p-orbitals do not overlap. Because they are unable to distribute their electrons to the other atoms in the molecule, p-orbitals that do not overlap are unable to participate in resonance.
Explanation:
The Hückels rule states that an aromatic molecule may only have 4n+2 electrons, where n is an integer. 4(1)+2=6 is a Hückel number for benzene. 8 is not a Hückel number, though. Cyclooctatetraene may be anti-aromatic given that it can satisfy all the other requirements.
A molecule will do whatever it can to cease being anti-aromatic, though, because it is so unstable and undesirable. Cyclooctatetraene, on the other hand, will bend and twist in order to become non-planar; as a result, it only satisfies two of the requirements and transforms into a much happier non-aromatic.
Because of its bending, twisting, and non-planarity, cyclooctatetraene's p-orbitals do not overlap. Because they are unable to distribute their electrons to the other atoms in the molecule, p-orbitals that do not overlap are unable to participate in resonance.
