Question

Match the following:

List-I (Mixture)		List-II (Separation Method)
A	\(\mathrm{CHCl_3}\) (b.p. \(334\,\mathrm{K}\)) + \(\mathrm{C_6H_5NH_2}\) (b.p. \(457\,\mathrm{K}\))	I	Steam distillation
B	Naphthalene + NaCl	II	Distillation
C	\(\mathrm{C_6H_5NH_2 + H_2O}\)	III	Sublimation
D	Organic compound present in aqueous medium	IV	Distillation under reduced pressure
		V	Differential extraction

The correct answer is

• A. A--II, B--I, C--III, D--IV
• B. A--II, B--III, C--I, D--V
• C. A--II, B--V, C--IV, D--III
• D. A--IV, B--III, C--II, D--I

Hint:

Remember: \[ \boxed{ \begin{aligned} &\text{Boiling point difference } \rightarrow \text{Distillation}, &\text{Volatile solid } \rightarrow \text{Sublimation}, &\text{Immiscible volatile liquid } \rightarrow \text{Steam distillation}, &\text{Organic compound in water } \rightarrow \text{Differential extraction}. \end{aligned} } \]

Answer 1

The Correct Option is B

Step 1: Match each mixture with the suitable separation method.& nbsp;

\[ \begin{aligned} A:& amp;\ \mathrm{CHCl_3+C_6H_5NH_2} & amp;& amp;\rightarrow \text{Distillation (II)},\\[2mm] B:& amp;\ \text{Naphthalene + NaCl} & amp;& amp;\rightarrow \text{Sublimation (III)},\\[2mm] C:& amp;\ \mathrm{C_6H_5NH_2+H_2O} & amp;& amp;\rightarrow \text{Steam distillation (I)},\\[2mm] D:& amp;\ \text{Organic compound in aqueous medium} & amp;& amp;\rightarrow \text{Differential extraction (V)}. \end{aligned} \]

Step 2: Write the correct matching.

Thus,

\[ \boxed{ A\rightarrow II,\; B\rightarrow III,\; C\rightarrow I,\; D\rightarrow V } \]

Hence, the correct option is

\[ \boxed{(B)}. \]
