1. Write a mechanism for the acid-catalyzed esterification that uses cyclopentanol and acetic acid.
2. Tertiary alcohols do not work well in the procedure outlined for this experiment; they give a different product from what you might expect. Explain this and draw the expected product from t-butyl alcohol (2-methyl-2-propanol).

using the IR, the 13C, and DEPT NMR spectra of your product
determine the identity of your unknown ester from a C-4 or C-5
alcohol. the identity of the C-4 or C-5 alcohol also needs to be
determined.

experiment:
1-butanol (n-butyl alcohol)
2-butanol (sec-butyl alcohol)
2-methyl-1-propanol (isobutyl alcohol)

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...

Practice: Show the product and mechanism for the hydration of cyclohexene in a reaction catalyzed by sulfuric acid. A similar reaction can be used to make ethers (instead of alcohols) using an alcohol (instead of water). This reaction is called alcoholysis of an alkene. Practice: Draw the product and mechanism for the alcoholysis of 2-methylpropene and methanol with sulfuric acid.
