Wesley Cole · Answer 1

c) ethyl 4-aminobenzoate

Explanation:

In an extraction by solvent, the solvent will dissolve solutes in the sample and will be recovery late. To dissolve the solutes, the solvent must have chemical similarities with them.

For example, polar solvents only dissolve polar solutes, nonpolar solvents only dissolve nonpolar solutes, acidic solvents only dissolve acidic solutes, and basic solvents only dissolve basic solutes.

So, if the extraction is being done with an acidic solvent, the acids will be extracted from the organic layer (the layer with an organic solvent which is the methylene chloride). The acids compounds are anthracene and benzoic acid. Then, they will be removed, and the majority of ethyl 4-aminobenzoate, which is a basic solvent, will remain in the organic layer.
