using the procedures, we used dichloromethane as the unknown
mixture and i was able to extract benzoic acid for an acid,
5-chloro-2-methoxyanaline for a base compound and biphenyl for
neutral compound.
i don't know if that answers the missing part but if it didn't
could you be specific please? thank you!

QUESTION:
Write a flow scheme for the work-up.
THE WORK UP:
C. Work-up (save all layers) and Isolation of Product MgBrCl Benzoic acid Transfer the mixture into a test tube. Rinse the beaker with about 3 mL of regular (not anhydrous) diethyl ether and pour the washings into the test tube. There should be two distinct layers in the test tube Remove the aqueous layer (to be discarded) and shake the ether layer with about 2 mL of 3 M...

please provide an equation for the reaction of the aqueous layer with Hdl. The following experiment was done: add 1g of 1:1 mixture of benzoic acid and naphthalene. add 30 ml of dichloromethane to dissolve. Add solution to a separatory funnel. Add 15ml of NaOH, shake and separate the two layers. with the aqueous layer, containing NaOH, combine 6M HCl until you have reached a pH of 2. ice to speed up the production of crystals.
