(a) Enumerate any two differences between simple distillation and fractional distillation.
(b) Draw a labelled diagram showing the process of fractional distillation.

Text Solution

Verified by Experts

(a) (i) Simple distillation can be used if the liquids to be separated differ in their boiling points by more than `25^(@)C`. If the difference is less, than fractional distillation can be used.
(ii) A fractionating column is needed for fractional distillation but not for simple distillation.
(b) For process of fractional distillation.
