Propene is an alkene with a double bond between 2 carbon atoms. $\ce{C3H6}$ may have 2 resonance structures due to 2 possible placings of the double bond. E.g. it can be C=C-C or C-C=C (ignoring hydrogen atoms).


Delocalized electrons are a result of resonance structures. Can propene have delocalized electrons?




Propene actually fulfil conditions for hyperconjugation (an alfa-CH adjacent to sp2 hybrid C atom) It is a delocalization of sigma bond electrons, also called no bond resonance. Mentioned C-H bond align in plane of the pi orbital. In such situation electrons of the sigma bond can be delocalized into the pi orbital. (Propene does not have resonance structures concerning only pi orbitals, as I suspect you think).


These are 3 "no bond resonance" structures of propene.
