Alkene d classification

An alkene containing a carbon-carbon double bond is called a monoolefin, and the general formula for a chain monoolefin is CnH2n. Olefins that contain more than one carbon-carbon double bond are called polyolefins. The polyolefin with the lowest number of carbon-carbon double bonds is diolefin or diolefin, which can be divided into three categories: two double bonds connected to the same carbon atom are called cumulative diolefin or bienes, and the number of such compounds is less; A diolefin in which two double bonds are separated by two or more single bonds is called an isolated diolefin, and its properties are similar to those of a monoolefins. A diolefin with two double bonds separated by a single bond is called a conjugated diolefin, and conjugated diolefin has some unique physical and chemical properties.
