Using the given figure, the ratio of \(R_t\) values of sample \(A\) and sample \(\mathrm{C}\) is \(\mathrm{x} \times 10^{-2}\). Value of \(\mathrm{x}\) is _______. (Image) Samples \((A, B, C)\) Fig : Paper chromatography of Samples
- A \(50\)
- B \(40\)
- C \(30\)
- D \(20\)
Answer & Solution
Correct Answer
(A) \(50\)
Step-by-step Solution
Detailed explanation
\(R_r \text { of } A=\frac{5}{12.5} \quad R_r \text { of } C=\frac{10}{12.5}\) \(\text { Ratio }=\frac{R_{f(A)}}{R_{f(C)}}=\frac{1}{2}=0.5 \text { or } 50 \times 10^{-2}\)
