What is collected in the flask at the end in steam distillation?

In $TLC$ for compound $X$,$R_f = 0.7$ and for $B$,$R_f = 0.4$. Which substance migrates more?

Given below are two statements: One is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: Thin layer chromatography is an adsorption chromatography.
Reason $R$: $A$ thin layer of silica gel is spread over a glass plate of suitable size in thin layer chromatography which acts as an adsorbent.
In the light of the above statements,choose the correct answer from the options given below.

Given below are two statements:
Statement $I$: Vapours of the liquid with higher boiling point condense before vapours of the liquid with lower boiling points in fractional distillation.
Statement $II$: The vapours rising up in the fractionating column become richer in high boiling component of the mixture.

The distillation technique most suited for separating glycerol from spent-lye in the soap industry is:

Which purification method is used to separate liquids that have a sufficient difference in their boiling points?
