Answer: (D) Partition chromatography. \textbf{Answer:} (d) Partition chromatography \textbf{Solution:} In paper chromatography the stationary phase is water held in the pores and fibres of the chromatography paper, and the components distribute (partition) between this stationary water and the mobile solvent.
- A.Thin layer chromatography
- B.Column chromatography
- C.Adsorption chromatography
- D.Partition chromatography✓
Correct Answer
(D) Partition chromatography
Solution & Explanation
\textbf{Answer:} (d) Partition chromatography \textbf{Solution:} In paper chromatography the stationary phase is water held in the pores and fibres of the chromatography paper, and the components distribute (partition) between this stationary water and the mobile solvent. Hence paper chromatography is a type of partition chromatography.
