Higher $R_f$ value means higher adsorption.

Vedclass · Answer

(C) The $R_f$ (retention factor) value is defined as the ratio of the distance traveled by the solute to the distance traveled by the solvent front. Since the solute cannot travel further than the solvent front,the $R_f$ value is always $\le 1$. $A$ higher $R_f$ value indicates that the substance has a greater affinity for the mobile phase and a lower affinity for the stationary phase (i.e.,lower adsorption). Therefore,the statement "Higher $R_f$ value means higher adsorption" is incorrect.

In chromatography,which of the following statements is incorrect for $R_f$?
