Lecture
This lecture covers elimination reactions in organic chemistry, focusing on E1 and E1CB mechanisms. It explains how these reactions proceed via charged intermediates and the factors that influence the choice between elimination and substitution reactions. The instructor discusses the importance of reaction conditions, leaving groups, bases, and temperature in determining the reaction pathway. Examples of non-nucleophilic bases are provided to illustrate their role in promoting elimination reactions. The lecture emphasizes the competition between elimination and substitution reactions, highlighting the conditions that favor each pathway. It concludes by summarizing the key concepts of polar reaction mechanisms and mentioning the relevance of radical reactions in polymer science.
