Introduction
A common method for synthesizing alkenes is by dehydrating
(removing the elements of water) an alcohol. The dehydration is
accomplished by heating the alcohol with either phosphoric or
sulfuric acid. In this experiment, the dehydration reaction is
illustrated by the conversion of 2-methylcyclohexanol to a mixture
of alkenes (remember the Saytzeff rule).
Information
Each step of this E1 elimination reaction is reversible and
thus, the reaction may be driven to completion by removing one or
more of the products,...

1. For each of the following pairs of solute and solvent, predict whether the solute would be soluble or insoluble. After making your predictions, you can check your answers by looking up the compounds in The Merck Index or the CRC Handbook of Chemistry and Physics. Generally, The Merck Index is the easier reference book to use. If the substance has a solubility...

If you conducted this experiment using (R) 2-bromobutane, what would be the stereochemistry of the product? How, if at all, would the stereochemistry of the product differ if the sodium iodide had not been included in the reaction mixture? This is the experiment: Formation of n-Butyl Acetate Just Below Reflux Set up a sand bath on a magnetic stirrer— start on “4” until it reaches 100°C To a 5-mL long-necked round-bottomed flask, add 0.750 g of sodium acetate trihydrate (NaOAc...
