Suggest the method for the purification of naphthalene.

In an aniline and water mixture,aniline can be separated by:

Which purification method is used to separate a volatile liquid from non-volatile impurities?

Match List-$I$ with List-$II$:

List-$I$ $(\text{Mixture})$	List-$II$ $(\text{Method of Separation})$
$A. CHCl_3 + C_6H_5NH_2$	$I. \text{Distillation under reduced pressure}$
$B. \text{Crude oil in petroleum industry}$	$II. \text{Steam distillation}$
$C. \text{Glycerol from spent-lye}$	$III. \text{Fractional distillation}$
$D. \text{Aniline-water}$	$IV. \text{Simple distillation}$

Choose the correct answer from the options given below:

Identify the correct statements from the following:
$(i)$ Electromeric effect is a permanent effect.
$(ii)$ Hyperconjugation is a temporary effect.
$(iii)$ Fractional distillation is used to separate two liquids from a mixture if the difference in their boiling points is less.
$(iv)$ Different compounds are adsorbed on an adsorbent to different extents.

The purification method based on the following physical transformation is $:$
$\text{Solid} (X)$ $\xrightarrow{\text{Heat}} \text{Vapour} (X)$ $\xrightarrow{\text{Cool}} \text{Solid} (X)$
