Question

In chromatography, which of the following statement is INCORRECT for R_f?

विकल्प

• R_f value depends on the type of chromatography.

• The value of R_f can not be more than one.

• Higher R_f value means higher adsorption.

• R_f value is dependent on the mobile phase.

Answer 1

Higher R_f value means higher adsorption.

Explanation:

In chromatography, R_f represents retardation factor.

`"R"_"f" = "Distance moved by the substance from baseline"/"Distance moved by the solvent from baseline"`

∴ Higher R_f value means lower adsorption.
