- BFractional Crystallisation
- ✓Steam distillation
- DSublimation
✓
Answer
Correct option: C.
Steam distillation
c
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.
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.
