Phenol on reaction with dilute nitric acid, gives two products. Which method will be most effective for large scale separation ?
- A Chromatographic separation
- B Fractional Crystallisation
- C Steam distillation
- D Sublimation
Answer & Solution
Correct Answer
(C) Steam distillation
Step-by-step Solution
Detailed explanation
Para product has higher boiling point than ortho as intermolecular \(H\)-bond is possible in former, where as intramolecular \(H\)-bond is possible in ortho product. Steam distillation can separate them as ortho product is steam volatile.
