title: Cyclopropenyl anion: an energetically nonaromatic ion.
abstract: A central idea in organic chemistry for the past 50 years is that cyclopropenyl anion is antiaromatic. A correlation between cycloalkene acidities and allylic bond angles reveals that energetically this is not case, cyclopropenyl anion is nonaromatic.
