What is the difference between distillation,distillation under reduced pressure and steam distillation?

Solution

Distillation is used in the case of volatile liquids with non-volatile impurities.
Distillation under reduced pressure is used purify liquids which decompose at their boiling point temperature.
Steam distillation is used steam volatile liquids associated with water immiscible impurities.
