Unlike saturated hydrocarbons, which contain only single bonds, alkenes possess this double bond, making them unsaturated and highly reactive. For example, butene can exist as 1-butene or 2-butene, with the latter capable of further classification into cis and trans isomers based on the spatial orientation of substituent groups around the double bond.
How Branching Alters Alkene Reactivity and Isomer Stability
This specific structural feature, known as a functional group, dictates the majority of the compound’s chemical behavior and physical properties. This electron cloud is relatively exposed and less tightly held, making it susceptible to attack by electrophiles.
The most common reaction is an addition reaction, where the pi bond breaks and atoms add across the double bond, converting the alkene into a saturated compound. A molecule containing a single double bond is classified as a mono-unsaturated alkene, whereas those with two or more double bonds are termed di-unsaturated or poly-unsaturated, respectively.
How Branching Alters Alkene Reactivity and Isomer Stability
Physical Properties and State The physical state of an alkene at room temperature ranges from gas to liquid, depending primarily on the molecular weight. This reactivity forms the basis for their extensive use in industrial manufacturing and biological synthesis.
