Unformatted text preview: HYDROPHILIC (water – loving) molecules, such as salt and sugar, form hydrogen bonds with water molecules. Sodium Chloride (NaCl) atoms are loosely held together by ionic bonds. Since each ion has a charge, they are attracted to water molecules and go into “solution.” Glucose (C6H12O6) contains many oxygen atoms and therefore many polar covalent bonds that are attracted to water molecules causing the sugar molecule to go into solution. HYDROPHOBIC (water-fearing) molecules lack oxygen and polar covalent bonds and therefore do not form hydrogen bonds with water molecules. Fats contain little oxygen and thus are not attracted to water....
