Question:
What is $R_f$ of B in the following reaction?
What is $R_f$ of B in the following reaction?
Show Hint
For Thin Layer Chromatography (TLC), the value of \( R_f \) gives a measure of the distance travelled by a compound relative to the solvent front.

- \( \frac{1}{2} \)
- \( \frac{2}{3} \)
- \( \frac{3}{4} \)
- \( \frac{4}{3} \)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The $R_f$ value represents the ratio of the distance travelled by the substance to the distance travelled by the solvent front. In this case, the distance for $B$ is 8 cm and for the solvent front is 12 cm. Hence, \( R_f \) is calculated as:
\[
R_f = \frac{{Distance travelled by B}}{{Distance travelled by Solvent front}} = \frac{8}{12} = \frac{2}{3}
\]
Thus, the correct value for \( R_f \) of B is \( \frac{2}{3} \).
