Water and dichloromethane are immiscible liquids, so their mixture is separated by differential solvent extraction. The mixture of the fused-ring ketone and 4-nitrophenol, two organic compounds of differing polarity, is separated by column chromatography. Kerosene and naphthalene differ in boiling point and are separated by fractional distillation. Glucose and sodium chloride dissolved together are separated by crystallisation. Hence item A pairs with differential solvent extraction, B with column chromatography, C with fractional distillation and D with crystallisation.
