Cycloheptatrien anion

WebO The conjugate base of cyclopentadiene (1) is an aromatic anion. The conjugate base of cycloheptatriene (1) is a nonaromatic anion. O f the conjugate base of cycloheptatriene (I1) was flat it would be antiaromatic. O The conjugate base of cycloheptatriene (11) is less stable due to aromaticity. WebCyclopentadiene is as acidic as ethanol, reflecting the stability of its 6 π-electron conjugate base. Salts of cycloheptatrienyl cation (tropylium ion) are stable in water solution, again reflecting the stability of this 6 π π -electron cation. Exercises 1. Draw the resonance structures for cycloheptatriene anion. Are all bonds equivalent?

Tropylium cation - Wikipedia

WebCycloheptatrienyl anion (tropylium anion) has 8 pi electron system, therefore it must be antiaromatic but the extra lone pair on the one carbon would cause that carbon to be become sp3 hybridized and put those extra elctrons in one of the sp3 orbitals. This would make it non-planar and non-aromatic.
