WebOne end of the alcohol molecules has so much nonpolar character it is said to be hydrophobic (literally, "water-hating"). The other end contains an -OH group that can form hydrogen bonds to neighboring water molecules and is therefore said to be hydrophilic (literally, "water-loving"). WebOnce wetted, hydrophilic filters do not allow the free passage of gases until the applied pressure exceeds the bubble point and the liquid is expelled from the pores of the membrane. Hydrophobic filters will not wet in water but will wet in low surface tension liquids, for example, organic solvents such as alcohols.
