whats the difference between hypercojugation and resononce ?

Expert Answer:

Hyperconjugation is delocalisation of sigma electrons of C-H attached directly to unsaturated carbon atom with an unshared p electrons and it is a permanent effect and stabilisation of cation depends on the number of alkyl groups attached to positive carbon or carb cation.Resonance is delocalisation of pi electons and so the carbon does not show properties of C=C or C-C bond.The polarity produced is +ve or -ve.
