Given below are two statements:
Statement-I: A mixture of aniline and chloroform can be separated by differential extraction.
Statement-II: Aniline can be separated from a mixture of aniline and water by steam distillation.
Show Hint
Steam distillation is used for compounds that are:
• Immiscible with water
• Volatile in steam
• Stable at boiling temperature
• Immiscible with water
• Volatile in steam
• Stable at boiling temperature

The Correct Option is A
Solution and Explanation
Concept:
Organic compounds are separated based on differences in solubility, volatility and chemical properties.
Differential extraction utilizes differences in solubility in two immiscible solvents, whereas steam distillation is useful for water-insoluble volatile compounds.
Step 1: Examine Statement-I.
Aniline is a basic compound and reacts with dilute mineral acids to form water-soluble salts. Chloroform does not react with dilute acids and remains in the organic layer. Therefore, by shaking the mixture with dilute HCl, aniline can be extracted into the aqueous layer while chloroform remains in the organic layer. Hence differential extraction can separate aniline and chloroform. Therefore Statement-I is correct.
Step 2: Examine Statement-II.
Aniline is only sparingly soluble in water and is steam volatile. Compounds that are immiscible with water but volatile in steam can be purified using steam distillation. Hence aniline can be separated from water by steam distillation. Therefore Statement-II is also correct.
Step 3: Choose the correct option.
Both statements are correct. \[ \boxed{\text{Both Statement-I and Statement-II are correct}} \]
