WebDehydration of Cyclohexanol Kaylie Manzano April 25, 2024 CHE 2612-OC1 Introduction The purpose of this experiment is to synthesize cyclohexanol from cyclohexane and phosphoric acid via E 1 reaction mechanism. An E 1 reaction is a type of reaction mechanism that exhibits first-order kinetics. E 1 reaction mechanisms stand for … WebAddition with 1,2- alkyl shift. Mechanism: Electrons from the C1-C2 π bond attack the hydrogen of HBr, expelling the bromide anion and leading to the formation of a carbocation (Step 1, arrows A and B). Note here that the carbocation preferentially forms on C2 (secondary) and not C1 (primary) since secondary carbocations are more stable.
