The (s) electrons of C–H bond of the alkyl group enter into partial conjugation with the attached unsaturated system or with the unshared p- orbital. katherine to halls creekWebHyperconjugation is a permanent effect. Ex: Hyperconjugation in ethyl carbo cation. One of the carbon-hydrogen bonds of the methyl group aligns in the same plane with the empty p -orbital of the positively charged carbon atom. The electrons of this C-H sigma bond then gets delocalised into the empty p orbital. katherine to humpty doo
