Current Question (ID: 21225)

Question:

$\text{Statement I: A mixture of chloroform and aniline can be separated by simple distillation.}$ $\text{Statement II: When separating aniline from a mixture of aniline and water by steam distillation aniline boils below its boiling point.}$

Options:

1. $\text{Statement I is false but Statement II is true.}$
2. $\text{Both Statement I and Statement II are false.}$
3. $\text{Statement I is true but Statement II is false.}$
4. $\text{Both Statement I and Statement II are true.}$

Solution:

$\text{Hint: A mixture of chloroform and aniline can be separated by simple distillation.}$ $\text{The simple distillation method is used in (i) Volatile liquids from non-volatile impurities and (ii) the liquids having sufficient difference in their boiling points.}$ $\text{Liquids having different boiling points vaporise at different temperatures. The vapours are cooled and the liquids so formed are collected separately.}$ $\text{Chloroform (b.p 334 K) and aniline (b.p. 457 K) are easily separated by the technique of distillation.}$ $\text{Aniline is separated by steam distillation technique from aniline-water mixture. In this process, aniline boils below its boiling point.}$
