General Organic Chemistry Question 9
Question 9 - 29 January - Shift 1
Following chromatogram was developed by adsorption of compound ’ $A$ ’ on a $6 cm$ TLC glass plate. Retardation factor of the compound ’ $A$ ’ is $\times 10^{-1}$.
Show Answer
Answer: (6)
Solution:
Formula: Retardation Factor
$R_f=\frac{\text{ Distance moved by the substance from base line }}{\text{ Distance moved by the solvent from base line }}$
$=\frac{3.0 cm}{5.0 cm}=0.6$ or $6 \times 10^{-1}$
