Structural needs for hyperconjugation

(i) Compound could comprise at least one Sp²-hybrid carbon of as well alkene alkyl carbocation or alkyl free radical.

(ii) ∝- carbon along with respect to Sp² hybrid carbon should have at least one hydrogen. If both these conditions are fulfilled after that hyper conjugation will occur in the molecule.

(iii) Hyper conjugation is of three types

(iv) Resonating structures due to hyperconjugation might be written involving "no bond" among the alpha carbon and hydrogen atoms.
