Why is 1H-pyrrol-1-ium non-aromatic? [closed]

It has 4n electrons and is completely conjugated. It should be anti aromatic.

Why is this compound non-aromatic?

• Pyrrole is aromatic because it has six electrons in its conjugated $\pi$ system. This thing has four. – Ivan Neretin Jan 26 '17 at 6:45
• @IvanNeretin This thing has 4 electrons, so it must be anti aromatic. Why it is non aromatic? – Arishta Jan 26 '17 at 9:13
• Why should it be antiaromatic? It does not even have a cyclic conjugated $\pi$ system anymore. – Ivan Neretin Jan 26 '17 at 9:17
• Not fully conjugated. There is a saturated atom in the cycle. – Oscar Lanzi May 7 '17 at 22:24

It is non-aromatic even though it has 4$\pi$ electrons because nitrogen cannot form five bonds. Hence delocalisation is not possible and so it is non aromatic.
