Vedclass · Answer

(C) The $R_{f}$ value is calculated using the formula:$R_{f} = \frac{	ext{Distance travelled by compound from base line}}{	ext{Distance travelled by solvent from base line}}$From the chromatogram:Distance travelled by compound $A$ from the base line $= 2 \, cm$Distance travelled by solvent front from the base line $= 5 \, cm$Therefore,$R_{f} = \frac{2}{5} = 0.4$Expressing this as $	imes 10^{-1}$:$0.4 = 4 	imes 10^{-1}$Thus,the value is $4$.

Using the provided information in the following paper chromatogram,calculate the $R_{f}$ value of $A$ .......... $\times 10^{-1}$.
