Why is cyclopropene non-aromatic while it has a 2 pi electron?

WebOct 30, 2024 · He told me that if the delocalized pi electrons of a cyclic compound can be denoted as 4n+2 where "n" is an integer, then the compound can be called aromatic. And in the case of cyclopropene, if the pi electrons were delocalized then there would be 2=4n+2, giving n=0, an integer.
