Pi bond

A Pi (π) bond is a type of chemical bond formed when two atoms share electrons in a way that involves the sideways overlap of p orbitals—regions where electrons are likely to be found. Unlike sigma (σ) bonds, which are head-on overlaps, π bonds create a bond above and below the line connecting the nuclei, providing additional strength and stability. They typically form in double and triple bonds alongside sigma bonds, playing a crucial role in determining the shape, reactivity, and properties of molecules like alkenes and benzene.
