# Why are pi bonds delocalized?

Apr 27, 2017

π Bonds are delocalized because their elections are not confined to a single atom.

#### Explanation:

For example, consider the π bond in ethylene.

Before the $\text{p}$ orbitals overlap, the $\text{p}$ electrons are confined to (or "localized" on) each carbon atom.

However, the electrons in the π bond are free to roam over both carbon atoms.

That is, the electrons in the π bond are "delocalized".
