alkenes definition chemistry
Alkane Nomenclature: Naming of organic structures, unlike biological classification, follows a rigid set of rules. The International Union of Pure and Applied Chemistry, abbreviated IUPAC, came up with a set of rules that follows the same standards worldwide, and is accepted among all chemists. Olefin, also called alkene, compound made up of hydrogen and carbon that contains one or more pairs of carbon atoms linked by a double bond. Olefins are examples of unsaturated hydrocarbons (compounds that contain only hydrogen and carbon and at least one double or triple bond). He evaporated a solution of Ammonium Cyanate to produce Urea. Organic Chemistry has undergone a substantial change since then. There are well over a million synthetic organic compounds. Organic Chemistry is defined as the Chemistry of Carbon and its compounds. Carbon is a Lego( like element. I use the analogy Lego’s because these atoms tend to form bonds with themselves creating different shapes. Like the two below, octane on the left and a steroid precursor on the right. The shapes are created by the chemical property of carbon to form 4 bonds. Video: Alkenes: Definition, Properties & Examples. Alkenes are organic compounds that are recognized by the double bonds that are present in their chemical structure. You can find alkenes in things such as rubber and plastic products that we use every day. AP Chemistry: Tutoring Solution / Science Courses. Acyclic monoolefins have the general formula CnH2n, C being a carbon atom, H a hydrogen atom, and n an integer. They are rare in nature but can be formed in large quantities through industrial processing. Alkenes are unsaturated hydrocarbons. They are hydrocarbons because they are made of only carbon and hydrogen atoms, and they are unsaturated because they have one or more double bonds in their chemical structure. Let's take a look at the general chemical structure of an alkene (RC=CR'). Olefins containing two to four carbon atoms per molecule are gaseous at ordinary temperatures and pressure; those containing five or more carbon atoms are usually liquid at ordinary temperatures. A type of chemical process typified by the exchange of one or more hydrogen ions, H +, between species that may be neutral (molecules, such as water, H 2 O; or acetic acid, CH... < Organic Chemistry. Alkanes are the simplest organic molecules, consisting of only carbon and hydrogen and with only single bonds between carbon atoms. Alkanes are used as the basis for naming the majority of organic compounds (their nomenclature). Alkanes have the general formula CnH2n+2. Organic Chemistry/Alkanes. Alkanes are the simplest organic molecules, consisting of only carbon and hydrogen and with only single bonds between carbon atoms. Alkanes are used as the basis for naming the majority of organic compounds (their nomenclature). Alkanes have the general formula CnH2n+2.
A compound made up of hydrogen and carbon that contains one or more pairs of carbon atoms linked by a double bond.
