Alkyne Synthesis by Double Dehydrohalogenation

Professor Dave explains the synthesis of alkynes using E2 reactions, focusing on vicinal and geminal dihalides. He discusses the use of strong bases like sodamide and the importance of excess base in reactions with geminal dihalides. The video also covers the formation of acetylide ions and their applications in further reactions, such as SN2, to create fully substituted alkynes.
