WebAlkanes, alkenes, and alkynes are all classified as hydrocarbons, because they are composed solely of carbon and hydrogen atoms. Alkanes are said to be saturated hydrocarbons, because the carbons are bonded to the maximum possible number of hydrogens – in other words, they are saturatedwith hydrogen atoms. http://www.chem.latech.edu/%7Ededdy/chem121/Alkene_Alkyne_Aromatic.htm raves in manchester tonight

WebTerminal alkynes, like acetylene itself, are mildly acidic, with p Ka values of around 25. They are far more acidic than alkenes and alkanes, which have p Ka values of around 40 and 50, respectively. The acidic hydrogen on terminal alkynes can be replaced by a variety of groups resulting in halo-, silyl-, and alkoxoalkynes. WebAn alkyne contains a triple bond between two carbon atoms.
