The correct statement among the following, for a "chromatography" purification method is :

Multiple Choice Options

  • A Rf of a polar compound is smaller than that of a non-polar compound.
  • B Non-polar compounds are retained at top and polar compounds come down in column chromatography.
  • C Organic compounds run faster than solvent in the thin layer chromatographic plate.
  • D Rf is an integral value.

Step-by-Step Verified Solution

Organic compounds run slower than solvent in thin layer chromatography. Rf is not an integral value. It is the ratio of distance travelled by the organic compound to that of solvent. Rf value of a polar compound is smaller than that of non-polar compound as the polar compound is retained more by the adsorbent than non-polar compound.
