| Also Known As | Double bond (C=C, C=O), triple bond (C≡C, C≡N), pi bond (component) |
What is Multiple Bond?
A chemical bond in which two atoms share more than one pair of electrons. Double bonds consist of one sigma and one pi bond; triple bonds consist of one sigma and two pi bonds. Multiple bonds are shorter, stronger, and restrict rotation around the bond axis.

A chemical bond in which two atoms share more than one pair of electrons. Double bonds consist of one sigma and one pi bond; triple bonds consist of one sigma and two pi bonds. Multiple bonds are shorter, stronger, and restrict rotation around the bond axis.
Multiple bonds are fundamental to: alkene and alkyne chemistry (electrophilic and nucleophilic additions), carbonyl chemistry (nucleophilic additions to C=O), aromatic stabilisation (delocalised π bonds), Diels-Alder cycloadditions, organometallic π-bonding (metal-alkene complexes), and biological m…
Compounds with multiple bonds often undergo addition reactions — releasing energy. Reactions of alkenes and alkynes with oxidising agents (O₃, KMnO₄, H₂O₂) can be exothermic or explosive. Carbon monoxide (C≡O) binds to haemoglobin and cytochrome enzymes, causing acute toxicity.
