In chromatography, which of the following statements is incorrect for R f ?
Options
- AHigher R f value means higher adsorption.
- BThe value of R f cannot be more than one.
- CR f value depends on the type of chromatography.
- DR f value of dependent on the mobile phase.
Correct answer
A. Higher R f value means higher adsorption.
Step-by-step solution
R f or Retention factor or Retardation factor = d i s t a n c e   m o v e d   b y   s p o t d i s t a n c e   m o v e d   b y   s o l v e n t For low polarity compounds, lower will be adsorption and the lower the value of adsorption higher will be R f value
