Delocalized electron in cyclohexene?

[chewchun]

Is there any?
I was taught that for delocalization of electron to occur, pi bond must be present.
But when i did a question on it, it says that there is no delocalization on cyclohexene.

Anyone mind teaching me how and why it occur?And how to identify delocalization of electrons?

Electrons are delocalized in benzene because a pi-bond NETWORK is created (if you want to draw the resonance structure of benzene, you'll see what I mean). In cyclohexene, there is only one pi-bond and so the electrons in that pi-bond are localized between those two carbon atoms.

Pardon me,but if there are two double bond side by side,then will there by delocalization?
And does delocalization= conductivity (which mean cyclohexene can't conduct electricity)?
