Q. Using the provided information in the following paper chromatogram :
image
the calculate $R _{ f }$ value of $A$ ____ $\times 10^{-1}$

JEE MainJEE Main 2021Organic Chemistry – Some Basic Principles and Techniques

Solution:

$R _{ f }=\frac{\text { Distance travelled by compound }}{\text { Distance travelled by solvent }}$

on chromatogram distance travelled by cmopound is $\rightarrow 2 cm$

Distance travelled by solvent $=5 cm$

So $R _{ f }=\frac{2}{5}=4 \times 10^{-1}=0.4$
