TLC analysis of a mixture having 3 components (A, B, C) using silica gel as the stationary phase gave following Rf values; for A = 0.72, B = 0.48, C = 0.20.
Regarding the above observations, which one of the following statements is not correct for column chromatography of the mixture?
TLC analysis of a mixture having 3 components (A, B, C) using silica gel as the stationary phase gave following Rf values; for A = 0.72, B = 0.48, C = 0.20.
Regarding the above observations, which one of the following statements is not correct for column chromatography of the mixture?
Show Hint
- A is the most non-polar component
- C is the most soluble component in mobile phase
- A will be eluted first
- C is the most strongly absorbed component
The Correct Option is B
Solution and Explanation
Step 2: So A is the most non-polar and is eluted first (statements 1 and 3 are correct).
Step 3: C has the lowest Rf, so it is the most strongly adsorbed on the column (statement 4 is correct) and spends the least time in the mobile phase, i.e. it is the LEAST soluble/mobile in the mobile phase.
Step 4: Statement 2 (C is most soluble in mobile phase) is therefore not correct.
Answer: (B) C is the most soluble component in mobile phase
