$X$ and $Y$ have $R_f$ values of $0.75$ and $0.25$ respectively. In column chromatography,which component is obtained first?

The species that exhibits the highest $R_f$ value in a thin layer chromatogram using a non-polar solvent on a silica gel plate is

Explain the process of steam distillation.

In the given $TLC$ plate,the distances of spots $A$ and $B$ from the base line are $4 \ cm$ and $6 \ cm$,respectively. The distance moved by the solvent front from the base line is $8 \ cm$. If the $R_f$ value of $B$ is $x \times 10^{-1}$ times that of $A$,find the value of $x$.

Glycerol is purified by

Which one of the following mixtures can be separated by steam distillation technique?
