WebThe more polar the compound, the more it will adhere to the adsorbent and the smaller the distance it will travel from the baseline, and the lower its R f value. Why is polarity important for chromatography? Polarity has a huge effect on how attracted a chemical is to other substances. The larger the charge difference, the more polar a molecule is.
