If I were trying to separate two compounds that eluted closely together. How would their
separation be affected if I accidentally performed my column chromatography with a crooked
column?
Step by step
Solved in 2 steps
- 2. What are mobile and Stationary phases in a chromatogram? Site their nature.Which compound elutes first and last in reverse chromatographyPlease 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.
- I found the Rf value in chromatogram A but I’m unsure how to find the lowest point for BSuppose two cations have the same Rf value. How might you resolve their prescense in a mixture using paper chromatography?Use a suitable model to explain how separation and identification of a mixture of organic compounds can be achieved with a thin layer chromatographic (TLC) technique.
- How could you prepare a sample of pure (S)-naproxen from a sample of racemic naproxen using chromatography?In Thin Layer Chromatography,why does the least polar of the analytes (biphenyl)have a higher Rf value and travel futhest in dichloromethabe(eluents)?Which of the following pairs of compounds would be most easily separated by thin layer chromatography: n-octyl alcohol and 1-octene, hexadecane and octadecane, or chlorobenzene and bromobenzene?
