Consider the compounds tert-butylcyclohexane and 4-tert-butylcyclohexanol. Using silica gel plates, which of the two compounds will have the higher Rf value when ethyl acetate is the developing solvent?

4 tert-butylcyclohexane will have the higher Rf value when ethyl acetate is used as the developing solvent because the 4-tert-butylcyclohexanol is the more polar compound that can form hydrogen bonds with the polar silica gel stationary phase.

this means less polar 4-tert-butylcyclohexanol will have a higher Rf
