Solution

The correct option is B

Adsorption chromatography


Explanation for correct option:

Option B. Adsorption chromatography:

  • In adsorption chromatography, the stationary phase is a finely divided solid adsorbent and the mobile phase is usually a liquid.
  • The process of separation depends upon the selective adsorption of components of a mixture on the surface of a solid.

Thin-layer chromatography

  • Thin-layer chromatography(TLC) is an adsorption chromatography that is used to separate non-volatile mixtures.
  • In TLC, the mobile phase moves by capillary action. In this the thin film stationary phase may be either a liquid or a solid and the mobile phase may be a liquid or a gas.
  • This type of chromatography is performed on a sheet of glass/plastic/aluminum foil i.e. coated with a thin layer of adsorbent material such as silica or cellulose.

Explanation for incorrect options:

Option A. The partition chromatography is based on the differential partitioning of components of a sample mixture between two phases – stationary phase and mobile phase.

Option C. It is a type of ion-exchange chromatography which depends on the electrical mobility of ions.

Thus options A, C, and D are incorrect.

Hence, the correct option is B. Thin layer chromatography is Adsorption chromatography.
