Alkenes
ALKENES are a group of HYDROCARBONS that have at least one DOUBLE BOND between carbon atoms.
Alkenes have names which end in "-ene". eg. Ethene & Propene
Just like ALKANES, ALKENES are an example of a HOMOLOGOUS SERIES - A group of compounds that have similar structures with the SAME GENERAL FORMULA.
The general formula for alkenes is CnH2n.
Alkene molecules are UNSATURATED because they contain TWO fewer hydrogen atoms than the ALKANE with the same number of carbon atoms.
The carbon-carbon DOUBLE BOND is known as the FUNCTIONAL GROUP of ALKENES and is denoted as C=C.
