In a Thin Layer Chromatography (TLC) experiment, the solvent front moves a distance of from the base — Practical Organic Chemistry and Purification Chemistry Question
Question
In a Thin Layer Chromatography (TLC) experiment, the solvent front moves a distance of $10\ cm$ from the baseline. If a compound has a Retention factor ($R_f$) of $0.65$, what is the distance (in cm) moved by the compound from the baseline?
Answer: 6.5
💡 Solution & Explanation
The Retention Factor ($R_f$) is defined as the ratio of the distance moved by the substance to the distance moved by the solvent front. $R_f = \frac{d_{substance}}{d_{solvent}} \implies 0.65 = \frac{d_{substance}}{10} \implies d_{substance} = 6.5\ cm$.
