Column I (Mixture of compounds)	Column II (Separation Technique)
A	H 2​ O /CH 2​ Cl 2​
B
C	Kerosene/Naphthalene
D	C 6​ H 12​ O 6​/NaCl

• A. A-(iii), B-(iv), C-(ii), D-(i)
• B. A-(i), B-(iii), C-(ii), D-(iv)
• C. A-(ii), B-(iv), C-(i), D-(iii)
• D. A-(ii), B-(iii), C-(iv), D-(i)

Answer 1

Answer: (D)

A-(ii), B-(iii), C-(iv), D-(i)

Answer 2

A. H2​O/CH2​Cl2​→ ii, CH2​Cl2​>H2​O (density) so they can be separated by differential solvent extraction.

C. Kerosene / Naphthalene → iv. Fractional distillation.
Due to different B.P. of kerosene and Naphthalene it can be separated by fractional distillation.
D. C6​H12​O6​/NaCl→ i. Crystallization.
NaCl (ionic compound) can be crystallized.
