1 3 5 7-cyclooctatetraene anti aromatic?

[wantVCUdental]

according to KBB page 369, this molecule (1 3 5 7-cyclooctatetraene) is anti-aromatic. i thought that's correct, because it has 8 pi electrons and all carbons are sp2, therefore planar...
but i remember in topscore or something, they said this thing isn't planar and therefore isn't anti-aromatic nor aromatic.
is topscore wrong?

it's not aromatic, huckles rule is 4n+2 electrons in pi orbitals. tetraenes would have 8, which is anti-aromatic, it would need 6 or 10 to be aromatic.

it has 8 pi electrons, and like stated above, fits the criteria of 4n, to be anti-aromatic. to avoid this state of anti-aromaticity (less stable then expected), it becomes non-planar, so it can be more stable then it would be in the anti-aromatic state. cyclooctatetraene can do this because it can fold, however other 6 carbon compounds that have 4n electrons and are planar can not and result in an anti-aromatic compound.....


thats how you should think of it.
