Acid-catalyzed dehydration of secondary and tertiary alcohols proceeds through an E1 mechanism. The first step is the protonation of the alcohol oxygen to form an oxonium ion. Dehydration of 3-methyl-2-butanol forms one major and two minor organic products. Draw the structures, including hydrogen atoms, of the three organic products of this reaction.
3-methyl-2-butanol ------->an oxonium ion
Homework Answers
Hydride shift (Carbocation rearrangement) gives a stabler carbocation and removal of Hd is preferred over Hc because it gives the Zaitsev (or Saytseff) product.

What is Zaitsev’s rule? Give the mechanism for the acid-catalyzed E1 reaction of 2-butanol. Give the mechanism for the base-catalyzed E2 reaction of 2-bromobutane. Draw all possible products. You expect three products from the elimination reaction 2-butanol. What are they? The E2 mechanism is a one-step mechanism. True or False? Explain. Which of these two alcohols would you expect to be more reactive under H3PO4/aqueous conditions? Why? Give the structure of the main product in both cases. 1-phenyl-1-propanol 1 -cyclohexyl-1-propanol...
what is the rate determining step in the E1 mechanism for the dehydration of an alcohol?...
what is the rate determining step in the E1 mechanism for the dehydration of an alcohol? a)addition of the halide b)dissociation of the alkyloxonium ion to a carbocation and water. c)protonation of the alcohol d)elimination (deprotonation) of the beta proton i think the correct answer is c because i remember hearing something about protonation in my lab, but i am still unclear. if soemkne can explain, that would be great
