Which Compound Elutes First in Column Chromatography?
A Less-Polar Solvent Is First Used to Elute a Less-Polar Compound. Once the Less-Polar Compound Is off the Column, a More-Polar Solvent Is Added to the Column...

Keeping this in consideration, which compound will elute first?
1 Expert Answer. A weak polar solvent would tend to elute the less polar molecules first. Thus, hexane would probably be the first to be eluted, since alkanes are SLIGHTLY less polar than alkenes.
Likewise, in what order will the compounds elute from a column in column chromatography? If these compounds were separated by column chromatography on silica gel, what would be the elution order? (top — comes off the column first, bottom — comes off last). As I get it, column chromatography is like TLC where in a silica gel the nonpolar compound comes out first.
Keeping this in consideration, what is the order of elution?
So elution order is the order that these broken down chemicals leave the GC column. For example C4 chemicals like Isobutane would generally "elute" before a C8 like Toluene.
Which compound is more polar in column chromatography?
The blue compound is obviously more polar than the yellow one - it perhaps even has the ability to hydrogen bond. You can tell this because the blue compound doesn't travel through the column very quickly. That means that it must adsorb more strongly to the silica gel or alumina than the yellow one.
