pi bond
This term is a technical designation used exclusively within chemistry and molecular physics. It describes a specific spatial arrangement of electron density that differs from the direct, head-on overlap found in sigma bonds. Because the overlap occurs laterally, pi bonds are generally weaker and more reactive than sigma bonds, which is a critical distinction when predicting the chemical behavior of alkenes and alkynes.
In a grammatical sense, this is a compound noun. While it follows standard English pluralization rules, it is almost always encountered in a scientific context where it is paired with its counterpart, the sigma bond, to describe the total bonding structure of a molecule.

Examples
A pi bond is generally weaker than a sigma bond.
The pi bond allows for the delocalization of electrons in benzene.
Wait, does the triple bond have two pi bonds or just one?
I need to remember that the pi bond is formed by side-on overlap.
The pi bond is susceptible to attack by electrophiles.
Rotation is restricted around the pi bond in alkenes.
