JEE Main 2024 — 5 April, Shift 2 — Question 83

Using the given figure, the ratio of $R_{f}$ values of sample $A$ and sample $C$ is $\mathrm{x} \times 10^{-2}$ . Value of x is $\qquad$ . Samples (A,B,C)

Fig : Paper chromatography of Samples

Answer: 50

Numerical answer — enter this value.

Step-by-step solution

$\mathrm{R}_{\mathrm{f}}$ of $\mathrm{A}=\frac{5}{12.5} \quad \mathrm{R}_{\mathrm{f}}$ of $\mathrm{C}=\frac{10}{12.5}$

Ratio $=\frac{\mathrm{R}_{\mathrm{f}(\mathrm{A})}}{\mathrm{R}_{\mathrm{f}(\mathrm{C})}}=\frac{1}{2}=0.5$ or

$50 \times 10^{-2}$
