cyclopropene= not aromatic because the carbon opposite the double bond is sp3?

cyclopropene with a positive charge opposite the double bond=aromatic because it is sp2 with an empty p orbital?

If an H- ion is removed from that third carbon then there will be an unoccupied p-orbital. For this reason, it is aromatic.

so cyclopropene with ALL of its H's...does NOT have a continuous pi system..correct?

because it will have sp3 carbon when no Hs are removed....makes it non aromatic

cyclopropene (non-aro due to sp3)
cyclopropene with a lone pair ( anti-aro)
cyclopropene with positive charge (non-aro)
