Question
Carbocations are frequent intermediates in the reactions we have been studying. Put a check mark next to every item below that a carbocation can do: Rearrange to a more stable carbocation. Lose a proton to form an alkene. Combine with a nucleophile. React with an alkene to form a larger carbocation. Which statement(s) is/are true of acid-catalyzed alcohol dehydrations? a) Protonation of the alcohol is a fast step. b) Formation of a carbocation from the protonated alcohol is a slow step. c) Rearrangements of less stable carbocation to more stable carbocations are d) Loss of a proton by the carbocation intermediate is fast step. e) All of these choices.Explanation / Answer
Which statement(s) is/are true of acid-catalyzed alcohol dehydrations?
A) Protonation of the alcohol is a fast step.
B) Formation of a carbocation from the protonated alcohol is a slow step.
C) Rearrangements of less stable carbocations to more stable carbocations are common.
D) Loss of a proton by the carbocation is a fast step.
E) All of the above----------------correct answer
==================
Acid-Catalyzed Dehydration.
here is elimination to take place,and requires a good leaving group.
Alcohols are leaving gatherings, however within the sight of corrosive,
they can be changed over into water, which is an astonishing leaving gathering.
In the event that a alcohol can frame a steady carbocation, the E1 system will be favored
