Since every carbon center shown has two electrons in the lower energy, bonding π orbitals, the energy of each system is lowered overall (and thus more stable), regardless of cation, radical, or anion.

WebJun 26, 2000 · Here we again have an anomaly in regards to allyl and the 2-propenyl anion stabilities. The 2-propenyl anion is predicted to be more stable. The FMO energy gap for the cyclopropenyl anion is smaller than for the cyclopropyl anion, indicating the antiaromatic character of the former. In organic chemistry, 1-propenyl (or simply propenyl) has the formula CH=CHCH3 and 2-propenyl (isopropenyl) has the formula CH2=C-CH3. These groups are found in many compounds. Propenyl compounds are isomeric with allyl compounds, which have the formula CH2-CH=CH2.
