13 kwi 2023 · Alkenes and alkynes are two different classes of unsaturated hydrocarbons. An alkene has one or more carbon-carbon double bonds, while an alkyne has one or more carbon-carbon triple bonds. The fewest carbon atoms possible in either an alkene or alkyne is two.

Alkene and alkyne compounds are named by identifying the longest carbon chain that contains both carbons of the double or triple bond. This longest chain is named by the alkane series convention: “eth-” for two carbons; “prop-” for three carbons; “but-” for four carbons; etc.
An alkyne is a hydrocarbon with one or more carbon-carbon triple covalent bonds. An unsaturated hydrocarbon is a hydrocarbon that contains less than the maximum number of hydrogen atoms that can possibly bond with the number of carbon atoms present. Structures of alkene and alkyne are given.
Alkenes and alkynes can be transformed into almost any other functional group you can name! We will review their nomenclature, and also learn about the vast possibility of reactions using alkenes and alkynes as starting materials.
Alkenes are the unsaturated hydrocarbons in which there is a double bond between two carbon atoms. In these compounds, unsaturation is due to the presence of the double bond . Alkenes have the general formula \(\ce{C_nH_{2n}},\) where \(n\) is the number of carbon atoms in the molecule.
18 sty 2022 · This chapter deals with the organic compounds that have multiple bonds between carbon atoms (alkenes, alkynes, and aromatic compounds), their structure, nomenclature, and reactions. The notion of the cis/trans (E/Z) configurations of molecules are represented.
Alkynes are prepared from 1,1- and 1,2-dihaloalkanes by double dehydrohalogenation. The reaction provides a means to generate alkynes from alkenes, which are first halogenated and then dehydrohalogenated.
