Post-lab Question #1 : On the top of page 27 of the lab manual, you are instructed to allow the Grignard reagent to cool after it is refluxed and prior to the addition of the carbonyl compound. Why is this important? What is the danger in adding the carbonyl compound to the Grignard reagent solution while it is still hot? (4 points) Post-lab Question#2: Ethanol is often present in technical grade diethyl ether. What effect would the use of technical grade diethyl ether (instead of the anhydrous diethyl ether that you used) have had on your experiment. Provide a chemical rationale for your explanation, citing any reactions. (2 points) Post-labQuestion#3: Provide a method/sequence of reactions for the synthesis of 3-methyl-3-pentanol starting from ethane only. You may use any reagents that you would like to, but all of the carbons in 3-methyl-3- pentanol must come from ethane. (4 points)
