The inductive effect of the alkyl group on a saturated carbon chain follows the order: (CH3)3C > (CH3)2CH- > CH3CH2-> CH3- When an alkyl group is attached to an unsaturated system such as double bond or a benzene ring, the order of inductive effect is actually reversed.This effect is called hyperconjugation effect or Baker-Nathan effect. Resonance effect … [Read more...] about Hyperconjugation Effect
