Answer & Solution
Correct Answer
(B) A — R B—S C—Q D—P
Step-by-step Solution
Detailed explanation
Glycerol from spent lye is separated by distillation under reduced pressure because glycerol decomposes at its normal boiling point. A mixture of benzoic acid and naphthalene dissolved in an organic solvent can be separated by differential extraction using aqueous…
