WebEthyne (C 2 H 2) is the first member of the alkyne family, with two carbon atoms connected by a triple bond. In organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbon-carbon triple bond. Like other hydrocarbons, alkynes are generally hydrophobic. Ethyne is more commonly known under the trivial name acetylene. WebThe most well-known alkyne is ethyne. The common name of ethyne (and the preferred name according to IUPAC) is acetylene. ... This means that the simplest method of converting an alkyne to the equivalent alkane is to add 4 hydrogen atoms (or 2 hydrogen molecules (H 2)). The addition of hydrogen to an unsaturated bond is called hydrogenation. swasam hospital chennai
