Cyclooctatetraene isA. aromatic antiaromaticB. nonaromaticC. non-existentD.

Answer» Correct Answer - 3
Cycloctatetraene is conjugated carbocyclic polyene. On the basis of the number of `pie^(-)s(8pie^(-)s` equal to `4npie^(-)s)` , it is expected to be antiaromatic But it is non aromatic as it is not planar. Nonaromatics are nonplanar completely/incompletely conjugated carbocyclic polyenes having `(4n+2)pi` or `(4n)pie^(-)s` whose stability is comparable to their open chains analogs.
