Class 11Chemistry3 Organic Chemistry: Purification and CharacterisationPurification of Organic Compounds
EasyMatch the type of mixture of compounds in Column-$I$ with the technique of separation/purification given in Column-$II$.
Column-$I$ Column-$II$ $A$. Two solids which have different solubilities in a solvent and which do not undergo reaction when dissolved in it $1$. Crystallisation $B$. Liquid that decomposes at its boiling point $2$. Distillation under reduced pressure $C$. Steam volatile liquid $3$. Steam distillation $D$. Two liquids which have boiling points close to each other $4$. Fractional distillation $E$. Two liquids with large difference in boiling points $5$. Simple distillation
| Column-$I$ | Column-$II$ |
|---|---|
| $A$. Two solids which have different solubilities in a solvent and which do not undergo reaction when dissolved in it | $1$. Crystallisation |
| $B$. Liquid that decomposes at its boiling point | $2$. Distillation under reduced pressure |
| $C$. Steam volatile liquid | $3$. Steam distillation |
| $D$. Two liquids which have boiling points close to each other | $4$. Fractional distillation |
| $E$. Two liquids with large difference in boiling points | $5$. Simple distillation |
(A-1, B-2, C-3, D-4, E-5) The correct matches are as follows:
$A$. Two solids with different solubilities in a solvent are separated by $1$. Crystallisation.
$B$. Liquids that decompose at their boiling point are purified by $2$. Distillation under reduced pressure.
$C$. Steam volatile liquids are separated by $3$. Steam distillation.
$D$. Two liquids with boiling points close to each other are separated by $4$. Fractional distillation.
$E$. Two liquids with a large difference in boiling points are separated by $5$. Simple distillation.
Thus,the correct sequence is $A-1, B-2, C-3, D-4, E-5$.
$A$. Two solids with different solubilities in a solvent are separated by $1$. Crystallisation.

$C$. Steam volatile liquids are separated by $3$. Steam distillation.
$D$. Two liquids with boiling points close to each other are separated by $4$. Fractional distillation.
$E$. Two liquids with a large difference in boiling points are separated by $5$. Simple distillation.
Thus,the correct sequence is $A-1, B-2, C-3, D-4, E-5$.
