The Chemistry of Cocaine by Brahmadeo Dewprashad Department of Science Borough of Manhattan Community College, The City University of New York Professor Martinez entered the classroom with a livelier step than usual. Her morning students were accustomed to their instructor's ritual of carefully unpacking her book bag and arranging the contents neatly on the desk before beginning a lecture. But this time Martinez simply set her bag down on the chair, turned to the class, and began. "Today,...

Explain why for condensation reactions occurring at the α-carbon you often use a weak base (like -OH) to create the enolate when for reactions such as halogenation you would use a strong base (like LDA). Under what conditions (give an example) could you use LDA for a condensation reaction? Explain as in-depth as possible and I will give you a thumbs up! Thanks :)
