CHEM 2211 1nd Edition Lecture 31Outline of Last Lecture I. E2 reactionsOutline of Current Lecture I. E1 reactions Current LectureE1 reactions: - Stand for elimination reactions- 1 for unimolecular Unimolecular: - Only one molecule is involved in the rate determining step. Rate law- Rate= k [alkyl halide] - The rate is linearly dependent on the concentration of the alkyl halide The E1 reaction is a two step reaction slow rate determining step first then a fast reaction to product. Mechanism: CH3 CH3(CH3)3C – Br CH2 – C – CH3 CH3=C – CH3 + H3O+ HH2OThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Only tertiary alkyl halides undergo E1 reactions For alkyl halides with the same alkyl group the order of most reactive to least reactive is: - RI- RBr- RCl-
