WebThe ethyl carbocation, CH 3-CH 2 + is more stable than the methyl carbocation, CH 3 +. This is because, the σ-electrons of the α-C-H bond in ethyl group are delocalized into the empty p-orbital of the positive carbon center and thus by giving rise to 'no bond resonance structures' as shown below. Whereas hyperconjugation is not possible in ... WebLet us take an example of ethyl carbocation (CH 3 CH 2 +) to understand hyperconjugation. In ethyl carbocation, the positively charged carbon atom has an empty p-orbital. One of the C−H bonds of the methyl group can lie in the plane of this empty orbital and the electrons responsible for the establishment of this C−H bond can then be ...
