Formation of benzene from alkane
WebFrom alkynes: Alkynes can be used for the preparation of alkenes. Alkyne to alkene conversion is carried out by the reduction of alkynes with hydrogen in the presence of palladised charcoal. The charcoal used is moderately deactivated with the help of quinoline or sulphur compounds. This reaction results in the formation of alkenes. WebIsomerism in saturated hydrocarbons is due to.
