QAIPMT-2005-Ch-2479: NEET 2005 Chemistry - Class 11 AIPMT-2005-Ch-2479 Solution: The best method for the separation of naphthalene and benzoic…
The best method for the separation of naphthalene and benzoic acid from their mixture is
Multiple Choice Options
- A distillation
- B sublimation
- C chromatography
- D crystallisation.
Step-by-Step Verified Solution
Sublimation would be the best method because
it is applicable for those organic compounds which
pass directly from solid to vapour state on heating
and vice versa on cooling. In these compounds
naphthalene is volatile and benzoic acid is nonvolatile due to the formation of dimer via intermolecular hydrogen
bonding.
