I have confusions arising due to incosistent facts all around internet some of them are as follow :
1.) Arguments for Cyclopropenyl Anion
a.) Wikipedia which under the heading of "Effects on reactivity" clearly states that :
"However, the cyclopropenyl anion has 4 π electrons in a cyclic system and in fact has a substantially higher pKa than 1-propene because it is antiaromatic and thus destabilized"
b.) This Answer on ChemSE which clearly states that its Non-Aromatic in Nature
c.) Also this NEPTL site which clearly states that:
Cyclopropene is not aromatic because one of its ring atoms is sp3 hybridized so it does not fulfill the criterion for aromaticity. But the cyclopropenyl cation is aromatic because it has an uninterrupted ring of p-orbital and (4n+2) π-system. The cyclopropenyl anion is antiaromatic as it has (4n) π-system.
2.) Arguments for cycloheptatrienyl anion
b.) Also my book (solomons and fryhle organic chemistry adapted for JEE) gives this as Antiaromatic
I don't know which one is correct, please help by providing a comprehensive answer with a reason that can be applied everywhere in such questions.
EDIT: Hello the one who closed the question can I ask the reason for closing as much I can do I abid by this guideline I asked my question straigthformward and then presented my research please tell me why my question is put on hold, I seek answers
