Distillation under reduced pressure is an essential purification technique in organic chemistry. For — Qualitative and Quantitative Analysis Chemistry Question

💡 Solution & Explanation

Distillation under reduced pressure is specifically used to purify liquids with very high boiling points and, critically, those liquids that would otherwise decompose if heated to their normal boiling points at atmospheric pressure. Aniline-water uses steam distillation, and naphthalene uses sublimation.
