Answer:
(A) Chloroform
Explanation:
When two non-miscible liquids are put in a separatory funnel, the denser liquid will be the bottom layer of the extraction.
An aqueous solution of benzoic acid will have a density somewhat higher than the density of the pure solvent, which is water (water density ≅ 1g/cm³).
- Chloroform has a density of 1.49 g/cm³
- Hexane has a density of 0.655 g/cm³
- Octane has a density of 0.703 g/cm³
- Diethyl ether has a density of 0.713 g/cm³
Chloroform is denser than water and is the densest among the options, so the correct answer is A).
