Question
Chapter 10.5, Problem 12E
Interpretation Introduction
Interpretation:The necessity to wash the organic phase with a solution of sodium bicarbonate should be determined and the gas evolved during when the products are rinsed with bicarbonate should be identified.
Concept introduction: After the synthesis, the key step is to work up that involves the isolation of the pure desired product. This may require some rinse with solvents that depend upon the nature of impurities.
If the impurities are acidic the basic solution is suggested while for basic impurities aqueous hydrochloric acid may be used up for dissolution and removal of any basic impurities.
