Interpretation:Purpose of usage of the ethereal solution to rinse and wash the product with bicarbonate solution as well as with saturated brine should be determined.
Concept introduction:Ethereal solution refers to the organic layer. 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. For impurities that are polar such as traces of moisture the brine solution that is also polar and of similar nature is an appropriate solvent.
