Question

1 what allows molecules be separated by column chromatography? check all that apply. check all that apply shape density size polarity

Explanation:

Column chromatography separates molecules based on their interaction with the stationary and mobile phases. Polarity affects how molecules interact with these phases. In size - exclusion chromatography (a type of column chromatography), size is a factor as smaller molecules can enter the pores of the stationary phase and take a longer path. Shape can also play a role in some types of chromatography as it can influence the flow through the column and interaction with the stationary phase. Density is not a characteristic that is typically used in column chromatography for separation.

Answer:

Shape, Size, Polarity
