When commonly sold as fuel it is also known as liquified petroleum gas (LPG or LP-gas) and can be a mixture of propane with smaller amounts of propylene, butane and butylene, plus ethanethiol as an odorant to allow the normally odorless propane to be smelled. In North America, propane is primarily a pure fuel with only the odorant added. It is used as fuel in cooking on many barbecues, portable stoves, and in motor vehicles. Propane powers some locomotives, buses, forklifts, and taxis and is used for heat and cooking in recreational v ...

An alkene in organic chemistry is an unsaturated hydrocarbon containing at least one carbon to carbon double bond. The simplest alkenes, with only one double bond, form a homologous series, the alkenes with general formula CnH2n. The simplest alkene is C2H4, which has the common name "ethylene" and the International Union of Pure and Applied Chemistry (IUPAC) name "ethene". Alkenes are also called olefins and vinyl compounds.

Alkene - Shape of Alkenes. As predicted by the VSEPR model of electron pair replusion, in the molecular geometry of alkenes the bond angles about each carbon in a double bond are about 120°, although the angle may be larger because of steric strain introduced by nonbonded interactions created by functional groups attached to the carbons of the double bond. For example, the C-C-C bond angle in propene is 123.9°. The alkene double bond is stronger than a single covalent bond and also shorter with an average bond length of 133 picometre.

Alkene - IUPAC Names. To form the root of the IUPAC names for alkenes, simply change the -an- infix of the parent to -en-. For example, CH3-CH3 is the alkane ethANe. The name of CH2=CH2 is therefore ethENe. In higher alkenes, where isomers exist that differ in location of the double bond, the following numbering system is used: Number the longest carbon chain that contains the double bond in the direction that gives the ca ...

Alkene - Addition reactions. Alkenes reacts in many addition reactions. Catalytic addition of hydrogen: Catalytic hydrogenation of alkenes produce the corresponding alkanes. The reaction is carried out under pressure in the presence of a metallic catalyst. Common industrial catalysts are based on platinum, nickel or palladium, for laboratory syntheses, Raney's nickel is often employed. This is an alloy of nickel and aluminium. This is the catalytic hydrogenation of ethylene to yield ethane: CH ...

Propane is not produced for its own sake, but as a byproduct of two other processes: natural gas processing and petroleum refining. The processing of natural gas involves removal of propane and butane from the natural gas to prevent condensation of these liquids in natural gas pipelines. Additionally, oil refineries produce some propane as a by-product of production of gasoline or heating oil. The supply of propane cannot be easily adjusted to account for increased demand because of the by-product nature of propane production. About 85% of U.S. ...
