| No. | Simple distillation | Fractional distillation |
| i. | If in a mixture the difference in boiling points of two liquids is appreciable/large, they are separated from each other using the simple distillation. | If in a mixture the difference in boiling points of two liquids is not appreciable/large, they are separated from each other using the fractional distillation. |
| ii. | Simple distillation assembly is used. e.g.
Mixture of acetone (b.p. 329 K) and water (b.p. 373 K) can be separated by this method. |
fractionating column is fitted in distillation assembly.
e.g. Mixture of acetone (b.p. 329 K) and methanol (b.p. 337.7 K) can be separated by this method. |
