Dehydration of Alcohols Dehydration of 2-Methylcyclohexanol Prelaboratory Mole Calculations Calculate the theoretical yield of the cyclohexenes products in both moles and grams. One mole of the starting alcohol gives one mole the mixture of isomers. You are using 1.0 mL of 2-methylcyclohexanol and 0.5 mL of the catalyst, H3PO4. No calculation is needed for the catalyst.

Convert Cyclohexanol to Cyclohexene via a Acid-Catalyzed Dehydration reaction 1. Why does the product ‘come over’ after being formed? Please think about the properties of the starting material and product. 2. If there was no acid present, would you expect to get a product? Why/why not? 3. If we start off with 10 molecules of the starting alcohol and only get an 80% yield, how many molecules will we find in the product flask? 4. Look up the concept of...
