+A pi bond is a type of [covalent bond](/wiki/covalent_bond) formed by the sideways overlap of atomic p-orbitals. This creates a region of electron density above and below the internuclear axis, distinct from stronger [sigma bonds](/wiki/sigma_bond). Pi bonds are fundamental to double and triple bonds, influencing molecular structure and reactivity.
