Methods of Preparation of Alkynes – Organic Chemistry Notes
General Methods of Preparation of Alkynes: By dehydrohalogenation of vicinal dihaloalkanes: The removal of hydrogen and halogen is called dehydrohalogenation. When vicinal dihalides are heated with an alcoholic solution of KOH, hydrogen and halogen atoms are removed from adjacent carbons and in two steps alkynes are produced. Dehalogenation of Tetrahaloalkanes: Tetrahaloalkanes on treated with active …
