I'd greatly appreciate if someone could clarify this for me.

Conjugated cyclooctane.....is it anti-aromatic or non aromatic.

Kaplan text pg 321 says anti-aromatic bc it has 4n pi electrons conjugated.

Topscore practice test 1 says it is not anti-aromatic and it is non-aromatic bc it is not planar.

Thanks!

I think one of the orgo Qs on topscore was wrong, (forgot if this is the one u talking about)

Anyways, in oder to be aromatic, it have follow huckel's rule, and conjugated, cyclic structure.
 
Thanks for your reply.

I know the aromatic rule (4n +2 pi electrons).

The two practice exams give different answers for conjugated double bonded cyclooctane. Does it comply with the anti-aromatic rule of (4n pi electrons)?

Kaplan is wrong. It is indeed nonaromatic because it is nonplanar.
