Question:

Paper chromatography is an example of:

Show Hint

Paper Chromatography is a type of partition chromatography. Chromatography paper contains water trapped in it, which acts as the stationary phase. The paper selectively retains different components according to their differing partition in two phases.

The Correct Option is B

Solution and Explanation

Paper chromatography is an example of Partition chromatography.

The principle of paper chromatography involved is partition chromatography, in which the substances are distributed or partitioned between the liquid phase and the stationary phase. Water is one of the phases, which is held in the pores of the filter paper used, while the other is the mobile phase which moves over the paper.

Purification of Organic Compounds

We commonly use these methods for the purification of substances:

  • Simple crystallization - The most common method that we use to purify organic solids.
  • Fractional crystallization - It is the process of separation of different components of a mixture by repeated crystallisations.
  • Sublimation - Certain organic solids on heating directly change from solid to vapor state without passing through a liquid state. These substances are sublimable. This process is sublimation.
  • Simple distillation - It is the joint process of vaporization and condensation.
  • Fractional distillation - It is the process to separate a mixture of two or more miscible liquids which have boiling points close to each other
  • Distillation under reduced pressure
  • Steam distillation
  • Azeotropic distillation
