Question

cylcopropenyl anion is
anti-aromatic due to _______ a : cyclic , b:conjugated ,4nπelectrons , d : all​

Answer 1

Answer:

The concept of antiaromaticity is an outgrowth of the well-entrenched notion or aromaticity. While 4n+2 π-electron systems are aromatic, 4n π-electron systems should be antiaromatic. That should mean that antiaromatic systems are unstable. The cyclopropenyl anion 1a has 4 π-electrons and should be antiaromatic.
