First Name: Lab Section: Last Name: Class Roll  Pre-lab questions for Experiment 9: Dehydration of cyclohexanol 1. Give the overall reaction for the dehydration of cyclohexanol. 2. Cyclohexanol is the limiting reactant in the above reaction. Starting with 3.5 mL of cyclohexanol, what is the theoretical yield (in grams) of cyclohexene? 3. If 2-methylcyclohexanol is subjected to El dehydration, two major products are formed. What are the two products (draw their structures - be careful that you don't draw duplicate structures)? Circle the one that is expected to be in higher yield, assuming that the Saytzeff rule is followed. 4. IR spectroscopy will be used to verify the isolated compound is the correct compound (cyclohexene). What stretches (presence and absence) will distinguish the product (cyclohexene) from the starting material (cyclohexanol)? Give the functional group and wavenumbers.
