Acetylenic hydrocarbons - Acetylene series hydrocarbons

Japanese: アセチレン列炭化水素 - あせちれんれつたんかすいそ
Acetylenic hydrocarbons - Acetylene series hydrocarbons

...General name for aliphatic unsaturated chain hydrocarbons with one triple bond. A group of compounds with the general formula C n H 2 n -2 , also known as acetylene series hydrocarbons. Two of the carbon atoms that make up the skeleton are triple-bonded, but all other carbon-carbon bonds are single bonds. For this reason, alkynes have a molecular formula with four fewer hydrogen atoms than alkanes with the same number of carbon atoms. In the IUPAC nomenclature system, alkanes are named by changing the ending "ane" of the alkane to "yne." ...
