Question

Given below is the developed chromatogram of a mixture of pigments.

$R_{f}$ values for x and y can be expressed as.

• A. $\frac{x}{z},\frac{y}{z}$
• B. $\frac{x}{y},\frac{y}{z}$
• C. xz, yz
• D. $\frac{z}{x},\frac{z}{y}$

Answer 1

Answer: (A)

$\frac{x}{z},\frac{y}{z}$

Answer 2

:

& Dis\tan cetravelledbysubs\tan cefrombaseline \\ & (x) \end{aligned}}{Dis\tan cetravelledbysolventfrombaseline(z)}$$ For x: $R_{f} = \frac{x}{z};$ For $y:R_{f} = \frac{y}{z}$
