JEE Mains · Chemistry · STD 11 - 8.3. Organic chemistry purification and characterization
Match items of column \(I\) and \(II\)
| Column \(I\) (Mixture of compounds) | Column \(II\) (Separation Technique) |
| \(A\) \(H _2 O / CH _2 Cl _2\) | \(I\) Crystallization |
| \(B\) \(Image\) | \(II\) Differential solvent extraction |
| \(C\) Kerosene/Naphthalene | \(III\) Column chromatography |
| \(D\) \(C _6 H _{12} O _6 / NaCl\) | \(IV\) Fractional Distillation |
- A \(A-(iii), B-(iv), C-(ii), D-(i)\)
- B \(A-(i), B-(iii), C-(ii), D-(iv)\)
- C \(A-(ii), B-(iii), C-(iv), D-(i)\)
- D \(A-(ii), B-(iv), C-(i), D-(iii)\)
Answer & Solution
Correct Answer
(C) \(A-(ii), B-(iii), C-(iv), D-(i)\)
Step-by-step Solution
Detailed explanation
\(A\). \(H _2 O / CH _2 Cl _2 \rightarrow\) \(ii\), \(CH _2 Cl _2> H _2 O\) (density) so they can be separated by differential solvent extraction.\(B\). \(C.\) Kerosene / Naphthalene \(\rightarrow\) iv. Fractional distillation. Due to different B.P. of kerosene and Naphthalene…
