Aromaticity in cyclic ketones

I have read that, cycloprop-2-ene-1-one is aromatic and cyclopent-2,4-dien-1-one is antiaromatic.
Basically this is visualized by visualizing the resonance structures of this.

Similarly if I apply this concept in para benzoquinone, I get that it is antiaromatic because of 4 conjugated $\pi$ electrons. But many sites on net say it is not aromatic. Where am I going wrong ?




Para-benzoquinone is antiaromatic, and tries to get out of antiaromaticity by disrupting the conjugation; i.e. lengthening the "single bonds" so that pi-overlap across these bonds is not very feasible. This effectively results in two seperate pi-bonds in the ring; hence the observed "non-aromaticity".


It does have antiaromatic characters though, in the sense that it is a strong oxidant, easily taking away two electrons from other molecules so that it can become the aromatic(6pi) hydroquinone diide anion.
