测试:GRE Subject Test: Chemistry
Chromatography involves the separation of a mixture by allowing a mobile phase to travel along a stationary phase. In thin layer chromatography (TLC), a liquid solution is able to travel along a stationary plate. The distance that a particular compound travels compared to another compound can be determined by comparing the Rffactors for each compound. The Rffactor is determined by dividing the compound's distance by the total distance of the solvent.
1. | Which of the following compounds would have the smallest Rffactor in a standard thin-layer chromatography (TLC) experiment? |
Propane
Glucose
Hexane
Butanol
