Hyperconjugation is defined as No bond resonance. The concept of hyperconjugation arose from the discovery of electron releasing pattern for alkyl groups. It involves `sigma` electrons of C-H bond. Greater the number of C-H bond (`alpha`-hydrogen atom w.r.t. double bond) more will be hyperconjugative structures, more will be stability Heat of hydrogenation of alkene are affected by hyperconjugative effects.
Which of the following is incorrect hyperconjugative structure?
