1. If 2-chloro-2-methylbutane is not properly dried over K2CO3 it will contain traces of water. A freshly prepared sample reacts neutral with pH-paper, but if the product is left at room temperature for a couple of weeks is will become acidic. How could one explain this observation?

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...

1. Procedure A. Lithium 2,6-dimethylphenoxide. In a 300-ml. flask, equipped with a magnetic stirrer and a reflux condenser and flushed with nitrogen, are placed 150 ml. of toluene (freshly distilled from sodium), 1.40 g. (0.202 mole) of lithium metal (Note 1) and 25.0 g. (0.205 mole) of resublimed 2,6-dimethylphenol. The mixture is heated under reflux with stirring for 36 hours; a nitrogen atmosphere is maintained for the reflux period (Note 2). The condenser is replaced by a distillation head with...
