Emily Rushton CHM 231-909 Professor N. Kemling 2008 March 12 Abstract Lab 5 – Dehydration of 2-Methylcyclohexanol 2-Methylcyclohexanol was dehydrated using an acid catalyzed reaction. The resulting product was then analyzed by gas chromatography to determine regiochemistry of the reaction, and to determine is Zaitsev’s rule, the product formed is the one with the most carbon constituents, was followed. 2.0 mL of 2- Methylcyclohexanol was distilled into a collection vial. .54grams of the reactant were obtained, thus producing a percent yield of 32.6% from 1.9 grams of the reactant. The water layer obtained from the sample was removed using a drying agent of

Unformatted text preview: anhydrous calcium chloride. 1.5m of the dried solution was inserted into the injection port of a gas chromatograph. The chromatogram found that both 3-Methylcyclohexene and 1-Methylcyclohexene were formed. 3-Methylcyclohexene had a retention time of 2.085, peak area of 14453, and 17.370% was formed in this reaction, making it the minor product. 1-Methylcyclohexene had a retention time of 2.621, a peak area of 64452 and 77.458% was formed in this reaction, making it the major product. According to this experiment, since 1-Methylcyclohexene was the major product, Grand Valley State University does indeed follow Zaitsevs rule....
