Represent hyperconjugation in $CH_3-CH_2^+$ and $CH_3-CH=CH_2$ by figure.
(N/A) Hyperconjugation involves the delocalization of $\sigma$ electrons of a $C-H$ bond of an alkyl group directly attached to an atom with an empty $p$-orbital or a $\pi$-bonded system.
$(a)$ In the ethyl carbocation $(CH_3-CH_2^+)$,the empty $2p$ orbital of the positively charged carbon overlaps with the $C-H$ $\sigma$ bond of the adjacent methyl group.
$(b)$ In propene $(CH_3-CH=CH_2)$,the $\sigma$ electrons of the $C-H$ bond of the methyl group overlap with the $\pi$ orbital of the adjacent double bond.
