4. You are given a mixture of sodium benzoate and cyclohexylammonium chloride (structures below) that are dissolved in water at pH 7.0. You enter the lab and quickly find a separatory funnel, an organic solvent, sodium hydroxide, concentrated hydrochloric acid, and water. Devise a way to separate these two molecules using a simple organic extraction method. Clearly indicate which molecule is in the organic layer and which molecule is in the aqueous layer. Justify your method by describing what is happening at the molecular level.
