Vedclass · Answer

(A) Hyperconjugation is the interaction of electrons in a sigma bond (usually $C-H$ or $C-C$) with an adjacent empty or partially filled $p$-orbital or a $\pi$-orbital to give an extended molecular orbital that increases the stability of the system.In option $A$,the delocalization of electrons from the $C-H$ sigma bond into the adjacent $\pi$-system is shown,which is the characteristic representation of the hyperconjugation effect (also known as no-bond resonance).Option $B$ represents the resonance effect (mesomeric effect).Option $C$ represents the inductive effect.Option $D$ represents an electrophilic addition reaction.Therefore,the correct representation of hyperconjugation is given in option $A$.

Which one of the following represents the hyperconjugation effect?
