(1) The functional group of an alkene is its carbon-carbon double bond.(2) Epoxidation, the conversion of an olefin (an unsaturated alkene hydrocarbon) to a cyclic ether through reaction with hydrogen peroxide, a peracid, or oxygen, is an important chemical technique.(3) By careful use of appropriate conditions and catalysts alkanes can be converted into other hydrocarbons such as the alkenes and alkynes.(4) Among the 4800 constituents of tobacco smoke, researchers have identified more than 100 alkanes, 150 alkenes and 55 alicyclic hydrocarbons.(5) This is one of the most common ways of synthesizing alkenes , double-bonded hydrocarbons.
