Correct Answer - Option 3 : Higher R
f value means higher adsorption.
Concept:
Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase.
The Rfvalue is defined as the ratio of the distance moved by the solute (stationary phase) and the distance moved by the solvent (mobile phase) along the paper.
1. Rf value depends on the type/medium of chromatography.
2. The value of Rf ranges from zero to one.
3. When the plate most rapidly, then the Rf value is higher while the adsorption is less.
4. Rf value is dependent on the mobile phase and stationary phase.
Thus, option (c) is the incorrect statement related to R
f.
