B.) Why did you use aqueous sodium bicarbonate (a weak base, baking soda) to wash the crude t-pentyl chloride? C.) Why did you not wash the crude t-pentyl chloride with aqueous sodium hydroxide (a strong base)? Hint: see question D). D.) Propose a mechanism for the formation of 2-methyl-2-butene from the reaction of t-
1. a) Aqueous sodium bicarbonate was used to wash the crude t-pentyl chloride in order to eliminate the polar impurities; mainly to get rid of the excess of HCL. Equation: HCl → NaCl + H2O + CO2. b) It would be undesirable to wash the crude halide with aqueous sodium hydroxide, because it's very polar and will act as a base by giving an elimination product or a nucleophile .
Jun 24, 2008· I..sodium bicarb is not difficult to deal with and 2 chloro2 methyl propane is t-butyl chloride easily prepared from t-butyl alcohol and HCl shaken in a separatory funnel. The NaHCO3 will neutralize the excess acid and will form NaCl which will help "salt out" the t-butyl chloride out of the aqueous phase to form a layer separate from the water ...
