Alkyne - Wikipedia
In organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbon —carbon triple bond. [1] . The simplest acyclic alkynes with only one triple bond and no other functional groups form a homologous series with the general chemical formula CnH2n−2.
Cycloalkyne - Wikipedia
Because of the linear nature of the C−C≡C−C alkyne unit, cycloalkynes can be highly strained and can only exist when the number of carbon atoms in the ring is great enough to provide the flexibility necessary to accommodate this geometry.
12.5: Alkenes and Alkynes - Chemistry LibreTexts
2023年4月13日 · 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.
Alkenes and Alkynes – Introductory Chemistry
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.
1: Alkenes and Alkynes - Chemistry LibreTexts
Alkynes are similar to alkenes in both physical and chemical properties. For example, alkynes undergo many of the typical addition reactions of alkenes. The International Union of Pure and Applied Chemistry (IUPAC) names for alkynes parallel those of alkenes, except that the family ending is -yne rather than -ene.
Alkynes and Synthesis – Master Organic Chemistry
2013年6月24日 · Alkynes can be used to synthesize alkanes. The method is simple: treat with a finely divided noble metal catalyst (palladium on carbon “Pd/C” is the usual choice, although finely divided platinum can also be used) along with hydrogen gas, and two addition reactions occur to give the alkane. Following this so far?
9.1: Naming Alkynes - Chemistry LibreTexts
2024年3月25日 · Alkynes are organic molecules made of the functional group carbon-carbon triple bonds and are written in the empirical formula of \(\ce{C_{n}H_{2n-2}}\). They are unsaturated hydrocarbons. Like alkenes have the suffix –ene, alkynes use the ending –yne; this suffix is used when there is only one alkyne in the molecule.
Alkynes - Softschools.com
Alkynes, sometimes referred to as acetylenes, are unsaturated hydrocarbons that contain a carbon to carbon triple bond. The two pi bonds in the carbon to carbon triple bond reduce the total number of possible hydrogens that can be attached to the alkyne. Thus, the generic formula for an alkyne is C n H 2n-2. The name alkyne (with suffix ~yne ...
