Question

Compare the column material of GC and LC in terms of the “functional groups” taking place on the column surface or on the packing material?

Draw chemical structure of the active groups and classify them according to their polarities.

Definition Definition Group of atoms that shape the chemical characteristics of a molecule. The behavior of a functional group is uniform in undergoing comparable chemical reactions, regardless of the other constituents of the molecule. Functional groups aid in the classification and anticipation of reactivity of organic molecules.
