Question

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, (sodium bicarbonate, caution: do not cap the separatory funnel until gas evolution stops) and (3) deionized water. (Note: You need to drain the aqueous layer after each wash. For the volumes of your aqueous washes, use approximately twice the volume of your organic layer.) The organic layer was then dried over Na2SO4, decanted into a 50 mL round bottom flask and purified by distillation. (See Figure 1 below. Can you explain what happens during a distillation?) The experimental distillation setup is shown below. Remember to record the yield and boiling point of your liquid product.

Answer 1

bulds up pressure aus. 5 Saturated Natio, lag.) is added to neutralize any remaining acidi Nahig is a basic compound so it can niutralize aacidie compounds and then removed in aqueous layer. The reaction between acid and base gives co, which bulds up pressure inside the funnel. Se obtien vc) is correct. CS Scanned 'with in CamScanner
