When a mixture of A and B were subjected to paper chromatography, A moved up higher than B. However, neither one moved as high as the solvent. Based on this fact, discuss. Relative strength of interactions between A and paper vs. A and solvent. Why? Relative strength of interactions between A and paper vs. B and paper. Why? Can you say anything about relative solubility of A vs. B in the solvent used (mobile phase)? Explain.

Please Explain clearly Why couldn’t you use acid-base extraction to separate a ketone and an alcohol? why do we use column chromatography instead? Please explain clearly the benefits of both methods and why is one method preferred over the other.
A student properly sets up a column chromatography experiment. Although the mixture is soluble in the mobile phase, the sample appears "stuck" at the top of the column and will not elute regardless of how much solvent is applied. What could be the cause of this problem and what could the student do to try and achieve a successful separation?
Determine the order of inhibition time of hexane, hexanol and benzene compounds in the reverse phase liquid chromatography column.
Compound A has a lower affinity for the stationary phase thancompound B and can dissolve well in the mobile phase. In theseparation of the mixture of A and B by column chromatography,which compound will be eluted first from the column? Explain
How does it affect the peak produced in gas chromatography when: – Inserting samples is too slow – Column temperature is too high
Use the following chromatogram and table as your data. Given that the mobile phase conditions of the experiment use a 70% acetonitrile:30% methanol mixture and the stationary phase is a C-18 column, what is the classification of the chromatography? planar reverse normal partition
a pigment in the thin layer chromatography traveled beyond or farther than the solvent front. Therefore, the Rf value of that certain pigment is greater than 1. What does this mean to the experiment?
please quickly ,within 1hour thanks ! If it takes longer than an hour, i don't need the answer (2) List the representative stationary phase for gas chromatography.
The following data give the recovery of bromide from spiked samples of vegetable matter, measuredusing a gas–liquid chromatographic method.
