Question

The paper is non-polar in paper chromatography.

(a) True

(b) False

This question was posed to me by my college director while I was bunking the class.

Question is from Chromatography in section Unit Operations of Bioprocess Engineering

Answer 1

The correct choice is (b) False

Best explanation: Polar components will be attracted to the water molecules attached to the cellulose (paper) and not attracted to a nonpolar solvent. The chromatogram will not contain the polar components, given that it doesn’t climb up the paper with the nonpolar solvent.
