Three organic compounds \(A , B\) and \(C\) were allowed to run in thin layer chromatography using hexane and gave the following result (see figure). The \(R_f\) value of the most polar compound is \(............\,\times 10^{-2}\)
- A \(24\)
- B \(25\)
- C \(23\)
- D \(22\)
Answer & Solution
Correct Answer
(B) \(25\)
Step-by-step Solution
Detailed explanation
More \(R _{ f }\), less its polarity \(R _{ f }=\frac{\text { Distance travelled by compound ' } X \text { ' }}{\text { Distance travelled by solvent ' } Y '}\) \(=\frac{2}{8}=0.25=25 \times 10^{-2}\)
