Why is the following compound not aromatic?

Question

Quizplus · Accepted Answer

In order for a compound to be aromatic, the pi electron system must be cyclic, planar, and have a continuous pi electron system with 4n+2 pi electrons. The compound given is not cyclic, therefore it cannot be aromatic. Choice A is incorrect because 4n pi electrons can potentially make a compound antiaromatic, not necessarily non-aromatic. Choice B is partially correct, but being cyclic is only one of the requirements for aromaticity. Choice C is also incorrect because it refers to the rule for Huckel's Rule, which is only applicable for monocyclic compounds.
