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. WebAlkynes are acidic because they can release hydrogen atoms to form alkyne ions. Therefore, the alkyne is used in the form of Brönsted-Lowry acid. As mentioned above, alkynes contain a triple-bonded carbon atom called sp. …

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. http://ccc.chem.pitt.edu/wipf/courses/2320_07_files/Wittig_Reaction.pdf WebHow do you test for an alkene? Unsaturated molecules are called alkenes. It is possible to use a basic bromine water test to know the difference between an alkane and an alkene. If the bromine reacts with the carbon-carbon double bond, the alkene can turn brown bromine water colourless. With alkenes and alkynes, bromine reacts quickly. phoenix crow
