It is the ratio of the distance traveled by a compound in a mobile phase compared with the distance traveled by the front of the mobile phase itself
What is Rf Value?
- Rf value is the ratio of the solute's distance travelled to the solvent's distance travelled.
Rf = migration distance of substance / migration distance of solvent front
- The word comes from chromatography when it was discovered that a given component will always travel the same distance in a given solvent under same conditions
- If we get 1 Rf value, it means the reaction is successful.
- But if we get 2 or more Rf values, then it means there is some impurity or side products or maybe some reactants are present in the final product.
