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.
Alkanes - Are saturated hydrocarbons that therefore contain only hydrogen and carbon atoms bonded to each other, and typically follow the chemical formula CnH2n+2. A common example is paraffin. 2. Alkenes - These unsaturated hydrocarbons are molecules that contain at least one carbon-to-carbon double bond. With the chemical formula consisting of molecules of CnH2n, alkenes are very common in the petrochemical industry; the simplest alkene is ethylene, or ethane. 3.
