Answer:
Benzoic acid, anthracene
Explanation:
If you have a compound with an aqueous layer and organic layer, they can be distinguished by adding distilled water. The aqueous layer increases in size.
Organic products are soluble in organic solvent (organic layer). Benzoic acid, anthracene are both acidic, therefore if you perform an extraction with acidic aqueous solution both would dissolve in the methylene chloride thereby remaining in the organic layer.
