A reaction work-up for an aqueous reaction mixture calls for extraction first with diethyl ether and then a wash with saturated aqueous sodium chloride. What two functions does the the saturated sodium chloride wash serve? (usually Brine is not added to the aqueous solution during the first extraction) Group of answer choices It pulls water from the organic layer to dry it. It helps force the organic compound into the organic layer. It degasses the solvent It changes the color...

1. What experimental difficulty would you encounter if you had neglected to include a drying step before evaporating the ether solution of the neutral organic compound? 1b. An extraction procedure specifies that an aqueous solution containing dissolved organic material be extracted twice with 10-mL portions of diethyl ether. A student removes the lower layer after the first extraction and adds the second 10-mL portion of ether to the upper layer remaining in the separatory funnel. After shaking the funnel, the...
