Answer:
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
