WebApr 7, 2024 · An increase in solvent polarity increases Rf values for two reasons: Moderately polar compounds have a greater attraction to the mobile phase. When equilibrating between a polar stationary phase and nonpolar eluent, a polar compound tends to favor the polar stationary phase and have a low Rf. WebPhenethyl alcohol, or 2-phenylethanol, is the organic compound that consists of a phenethyl group (C 6 H 5 CH 2 CH 2) attached to OH. It is a colourless liquid that is slightly soluble in water (2 ml/100 ml H 2 O), but miscible with most organic solvents. It occurs widely in nature, being found in a variety of essential oils.
