KnowraPi bondLinked fromLinked fromThe 31 pages that link to Pi bond, each with the reason it gives.All 31Broader topic 9Related 19Narrower topic 1Compared with 2AlkeneBroader topic: The alkene double bond contains a pi bond that reacts more readily than its sigma bond.Conjugated systemBroader topic: Its p orbitals overlap along a conjugated chain, spreading π electrons across multiple atoms.Cis–trans isomerismBroader topic: Breaking its orbital overlap is required for unrestricted rotation around an alkene double bond.ChromophoreBroader topic: Pi electrons in many chromophores participate in light-driven electronic transitions.Electrophilic additionBroader topic: Its exposed electron density makes it more accessible to electrophiles than a sigma bond.Carbon–carbon bondBroader topic: Double and triple carbon–carbon bonds add one or two pi bonds.EtheneBroader topic: Its π bond makes ethene's double bond reactive toward addition.PropadieneBroader topic: Each of propadiene’s two carbon–carbon double bonds contains a pi bond.Double bond ruleBroader topic: Weak sideways overlap is the rule’s central explanation for unstable heavier-element multiple bonds.
