ChemistryOrganic Chemistry - Some Basic Principles and TechniquesJEE Main

Compare List I and List II and give the correct matching.

List I: (A) Glycerol, (B) o-Nitrophenol, (C) Anthracene, (D) Halogens, (E) Molecular weight List II: (1) Sublimation, (2) Beilstein's test, (3) Victor Meyer's method, (4) Steam distillation, (5) Vacuum distillation, (6) Eudiometry

Answer: A–5, B–4, C–1, D–2, E–3

Solution

Glycerol is a high-boiling liquid that decomposes near its normal boiling point, so it is purified by vacuum distillation (A–5). o-Nitrophenol is steam-volatile (intramolecular H-bonding) and is purified/separated by steam
