What might happen to your reaction if your glassware is wet (because you washed

Question

What might happen to your reaction if your glassware is wet (because you washed it the same day as the reaction was conducted)? Why might you expect a poor yield of alkene products if the dehydration reaction was earned out using hydrochloric acid as the catalyst? What is the purpose of the calcium chloride used in this experiment? Provide a mechanism to explain how methylenecyclohexane can form in your reaction. Why might you not see all four of the suggested products in your GC analysis? What is the purpose of extracting the product mixture with water before extracting with sodium bicarbonate solution? Based on your analysis of elimination mechanisms from the prelab, suggest an explanation for the differences in the products from the first sample collected from the reaction compared to the second sample. What products would you expect in the dehydration of 3-methylcyclohexanol if it were to undergo an E2 elimination? What about an E1 elimination?

Explanation / Answer

1. The dehydration reaction is removal of water molecules. Infact, a water-scavenging agent (H2SO4 or CaCl2) is also used. However, if the glassware is wet because it was washed, the water molecules will be present. This may cause incompletion of reaction or the reaction may not take place at all.
