Do Polar Or Nonpolar Compounds Travel Faster On Silica Gel?
Do Polar Or Nonpolar Compounds Travel Faster On Silica Gel? The separation occurs due to the polar OH groups on silica surface, polar compounds travel down the column more slowly than non-polar ones, as the hydrogen bonding interaction they make with the silica gel surface slows them down. Do polar or nonpolar substances elute faster?
