WebRearrangements can occur during the dehydration of 1° alcohols eventhough no 1° carbocation is formed—that is, a 1,2-shift occurs as the C—OH2+ bond is broken, forming a more stable 2° or 3° carbocation, asshown in Equation [1]. Using this information, draw a stepwisemechanism for the reaction shown in Equation [2]. According to the IUPAC, a carbocation is any cation containing an even number of electrons in which a significant portion of the positive charge resides on a carbon atom. Prior to the observation of five-coordinate carbocations by Olah and coworkers, carbocation and carbonium ion were used interchangeably.
