Which of the following compounds can be separated by the steam distillation method?

Which are the methods of purification of organic compounds?

$A$ liquid compound $(x)$ can be purified by steam distillation only if it is

On heating,some solid substances change from solid to vapour state without passing through liquid state. The technique used for the purification of such solid substances based on the above principle is known as

Using the given figure,the ratio of $R_f$ values of sample $A$ and sample $C$ is $x \times 10^{-2}$. The value of $x$ is . . . . . . . .
