Vedclass · Accepted Answer

In the soap industry,glycerol is separated by fractional distillation.

Vedclass · Answer

(D) $1$. Ortho-nitrophenol is steam volatile due to intramolecular hydrogen bonding,while para-nitrophenol is not due to intermolecular hydrogen bonding. Thus,they are separated by steam distillation. (Correct)$2$. Fractional distillation is used when the difference in boiling points is small (less than $20\,^{\circ}C$ to $30\,^{\circ}C$). The statement mentioning $10\,^{\circ}C$ is generally acceptable in this context. (Correct)$3$. Aniline is sensitive to high temperatures and decomposes before boiling at atmospheric pressure; therefore,it is purified by steam distillation. (Correct)$4$. Glycerol is separated from spent lye in the soap industry by distillation under reduced pressure,not by fractional distillation. (Incorrect)

List-$I$ (Purification technique)	List-$II$ (Mixture of organic compounds)
$(A)$ Distillation (simple)	$(I)$ Diesel + Petrol
$(B)$ Fractional distillation	$(II)$ Aniline + Water
$(C)$ Distillation under reduced pressure	$(III)$ Chloroform + Aniline
$(D)$ Steam distillation	$(IV)$ Glycerol + Spent-lye

Item $I$	Item $II$
$a$. Benzaldehyde	$p$. Mobile phase
$b$. Alumina	$q$. Adsorbent
$c$. Acetonitrile	$r$. Adsorbate
