Structure, Nomenclature, and Isomerism of Alkenes

Alkenes are hydrocarbons that have a C=C double bond. They are also known as olefins or as unsaturated compounds. They are referred to as unsaturated because the C atoms in a C=C double bond don't have enough hydrogens bonded to them as that of an alkane molecule has. Molecules having one carbon double bond are called monounsaturated compounds. Molecules with different double bonds are termed as polyunsaturated compounds.

Alkenes are the simplest compounds of the unsaturated hydrocarbons, hydrocarbons which will react with hydrogen. Alkenes contain at least one reactive double bonds between carbon atoms, and are easily represented by the symbol “=”. As we are familiar with the fact that a double bond consists of two carbon atoms. The simplest alkene is C2H4 or H2C=CH2, ethene.

The presence of a double bond is shown by the difference in completion from - ane to - ene. A more established form of the name, ethylene, is used in the chemical industry. The general formula is CnH2n. All alkenes have at any rate one double bond
