Before the p orbitals overlap, the p electrons are confined to (or localized on) each carbon atom. Within these higher order molecular orbitals, the electrons have greater degrees of freedom.

That is, the electrons in the π bond are delocalized.
Pi bond delocalization. Scalar fields provide an intuitive picture of chemical bonding. View delocalization_of_pi_pi_bond.pdf from chm inorganic at universiti teknologi mara. Why are pi bonds delocalized?
We say that the π electrons are localized. Delocalization is a term that refers to the distribution of nonbonding pi electrons through a molecule. Discover (and save!) your own pins on pinterest
Delocalized pi bonds are pi bonds that can be moved around in different resonance structures. An electron shared by more than two atoms is said to be delocalized. Instead of staying with one atom, electrons in a delocalized pi bond visit two.
A delocalized π bond is a π bond in which the electrons are free to move over more than two nuclei. Any orbital or bond that is aligned with a pi bond can result in stabilization through delocalization, by resonance or hyperconjugation. However, the electrons in the π bond are free to roam over both carbon atoms.
A delocalized pi bond is a pi (π) bond is one in which electrons can move freely between more than two nuclei. This can be seen in resonance structures like benzene, c6h6, where there is a ring of electrons from delocalization. Why are pi bonds delocalized?
Delocalization of electrons constitute a current in the molecule which leads to an increase in randomness/ entropy in the molecule that leads to stability. Before the p orbitals overlap, the p electrons are confined to (or localized on) each carbon atom. Localized electrons exhibit normal behavior, a localized lone pair remains close to one atom, and a localized bond pair travels between two atoms.
Resonance hybrids necessarily contain some abnormal electrons. The term delocalization refers to electrons that are not associated with a single atom or a covalent bond. The is achieved by orbital overlap to form higher order molecular orbitals.
Therefore, we can describe delocalized electrons as the nonbonding electrons in that chemical compound. That is, the electrons in the π bond are delocalized. However, the electrons in the π bond are free to roam over both carbon atoms.
Interestingly, the pi bonds in a conjugated system always will be found on the same plane as each other, because only that way will there bring about delocalisation of the pi electrons, in which they can freely move about the whole conjugated system instead of being tied down to a specific bond, thus lowering the overall energy of the system. In a delocalized pi bond, instead of sticking near one atom, it visits two atoms. I think delocalized pi bonds occur as unhybridized p orbitals may overlap and the electrons are not localized to a specific atom;
Delocalization of pi π bond mot revealed one of the most admiring qualities of bonded atoms. Localized electrons behave normally, and a localized lone pair stays close to one atom. How many pi bonds does no2 have?
Table of contents examples of the delocalized pi bond In a molecule like ethylene, the electrons in the π bond are constrained to the region between the two carbon atoms. In particular, the electron localization function (elf) has proven to be highly valuable in interpreting a broad range of bonding patterns.
