This episode discusses the controversy over the carbocation in organic chemistry in the 1950s, and experiments done to resolve the argument through the early 1960s, using superacids, especially in research by George Olah, William von Eggers Doering, and Lawrence H. Knox. We mention the main proponent, Saul Winstein and the main nay-sayer, Herbert Brown. We also take you through the basics of what a superacid is--and is not--and how dangerous superacids can be in the laboratory.
