JEE Mains · Chemistry · STD 11 - 8.3. Organic chemistry purification and characterization
The correct match between item \(I\) and item \(II\) is
| Item \(I\) | Item \(II\) |
| \((a)\) Benzaldehyde | \((p)\) Mobile phase |
| \((b)\) Alumina | \((q)\) Adsorbent |
| \((c)\) Acetonitrile | \((r)\) Adsorbate |
- A \(a\, \to \,q,\,\,b \to \,p,\,\,c \to r\)
- B \(a\, \to \,r,\,\,b \to \,q,\,\,c \to p\)
- C \(a\, \to \,q,\,\,b \to \,r,\,\,c \to p\)
- D \(a\, \to \,p,\,\,b \to \,r,\,\,c \to q\)
Answer & Solution
Correct Answer
(B) \(a\, \to \,r,\,\,b \to \,q,\,\,c \to p\)
Step-by-step Solution
Detailed explanation
Acetonitrile is used as mobile phase for most of the reverse chromatography. Benzaldehyde is adsorbed on alumina.
