Chemistry Question on Organic Chemistry- Some Basic Principles and Techniques
Which technique among the following, is most appropriate in separation of a mixture of 100 mg of p-nitrophenol and picric acid?
A
Steam distillation
B
2-5 ft long column of silica gel
C
Sublimation
D
Preparative TLC (Thin Layer Chromatography)
Answer
Preparative TLC (Thin Layer Chromatography)
Explanation
Solution
Thin layer chromatography is a technique used to isolate non-volatile mixtures.
Hence, mixture of p-nitrophenol and Picric acid is separated by TLC.
So, the correct option is (D): Preparative TLC (Thin Layer Chromatography).
