Alkynes (earlier called acetylenes), are those unsaturated hydrocarbons containing a carbon-carbon triple bond (-C C-). A general formula C n H 2 n - 2 , can represent alkynes. Alkynes posses four hydrogen atoms less than the alkane and two hydrogen atoms less..

Alkenes are named after the parent alkane by replacing '-ane' of the alkane by '-ene'. Alkynes are named after the parent alkane by replacing the suffix '-ane' of the alkane by '-yne'. Thus, Suffix for alkenes: -ene Suffix for alkynes: -..

Haloalkanes can be prepared by the addition of halogen acids (HBr, HCl or HI). In the addition of halogen acids to unsymmetrical alkenes, Markownikoff's rule is followed in which 'the negative part of the attacking reagent attaches itself to the carbon atom carrying lesser number of ..

Carbon-carbon triple bond, C=C, is a combination of one and two bonds. Alkynes give electrophilic addition reactions as they show reactivity due to the presence of bonds. This property is similar to alkenes but alkynes are less reactive than alkene..

trans-2-Butene cis-2-butene In the hydrogenation of cis- and trans-2-butene, both alkenes react with hydrogen to give the same product, butane. Since cis-2-butene is less stable than trans-2-butene by 0.66 kcal/mol, the energy diagram shows the cis alkene at a higher energy leve..

Laboratory Preparation of Alkynes - There are only a few methods available for the preparation of alkynes, in contrast to alkanes and alkenes. These are given bel..

General Chemical Properties of Alkynes - Alkynes contain a triple bond ( ). A triple bond has one and two bonds. Some characteristic reactions of alkynes ar..
