Question

Three organic compounds $A$, $B$ and $C$ were allowed to run in thin layer chromatography using hexane and gave the following result (see figure). The $R_{f}$ value of the most polar compound is $\qquad$ $	imes 10^{-2}$.\

Professor PC Thomas Classes · Answer

(25) : $C$ is most polar as it moved least in non-polar solvent.\ $R_{f}=\frac{	ext { Distance travelled by compound ' } C 	ext { ' }}{	ext { Distance travelled by solvent }}=\frac{2}{8}=0.25$ $$ =25 	imes 10^{-2} $$
