Cyclopropyl carbocation stability

WebNow, coming to the stability of cyclopropyl methyl carbocation, it is symmetrically stabilized by both C − C σ (2-3 and 2-4) bonds. You may call it bent bond resonance with the vacant p orbital of the carbocation. It is worth mentioning that cyclopropyl group stabilizes an adjacent postive charge even better than a phenyl group. WebThe reason more alkyl groups (“R” groups) stabilize the carbocation is because of two factors, called inductive effects and hyperconjugation. Inductive effects are relatively simple, it just means that alkyl groups are slightly electron rich and can donate some of this small electron density in to stabilize the carbocation.
