Just Answer Question 5
Synthesis of 2-chloro-2-methylbutane (literature version) Concentrated aqueous hydrochloric acid (HCI, 3.3 equivalents) was slowly added to 2-methyl-2-butanol (1.0 equivalents) in a 100 mL round bottom flask with stirring. The reaction was stirred for 15 minutes at room temperature. Upon completion, the reaction mixture was transferred to a 60 mL separatory funnel and the aqueous layer was removed. The organic layer (i.e. the product) was successively washed with: (1) saturated aqueous NaCl (brine), (2) saturated aqueous NaHCO,...

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
