The Paperwork Reduction Act of 1980 (Pub. L. No. 96-511, 94 Stat. 2812, codified at 44 U.S.C. Â§Â§ 3501 â 3521) is a United States federal law enacted in 1980 designed to reduce the total amount of paperwork burden the federal government imposes on private businesses and citizens.
Alkanes, Alkenes & Alkynes. Alkanes, alkenes and alkynes are simple hydrocarbon chains with no functional groups. Alkanes are identified because the carbon chain has only single bonds. Common alkanes include methane (natural gas), propane (heating and cooking fuel), butane (lighter fluid) and octane (automobile fuel). Alkenes have at least one double bond and alkynes have at least one triple bond. The most common alkyne is ethyne, better known as acetylene. The generic formula for alkanes is C n H 2n+2, where n is the number identified by the prefix. Alkenes have the formula C n H 2n and alkynes use the formula C n H 2n-2.
In organic chemistry, an alkene is an unsaturated hydrocarbon that contains at least one carbon âcarbon double bond. Alkene, olefin, and olefine are used often interchangeably (see nomenclature section below).Acyclic alkenes, with only one double bond and no other functional groups, known as mono-enes, form a homologous series of hydrocarbons with the general formula C n H 2n.ike a single covalent bond, double bonds can be described in terms of overlapping atomic orbitals, except that, unlike a single bond (which consists of a single sigma bond), a carbonâcarbon double bond consists of one sigma bond and one pi bond.
