JEE Main 2024 Chemistry question
On a thin layer chromatographic plate, an organic compound moved by 3.5 cm, while the solvent moved by 5 cm. The retardation factor of the organic compound is × 10⁻¹.
Answer: 7
Solution
= distance travelled by solute/distance travelled by solvent = 3.5/5 = 0.7 = 7 × 10⁻¹.
