Water molecules are polar molecules ... This means that the molecule itself is non-polar due to symmetry.
Opposite polar ends of molecules attract and hold one molecule to another. Alcohol has one O–H bond which is polar, but a large portion of the molecule is made up of C–H bonds which are nonpolar.
Substances that, like water, are polar and hence dissolve readily in water are hydrophilic. Conversely, nonpolar molecules do not dissolve readily in water and are hydrophobic. The basic behavior ...
The sucrose molecules dissolve as they are separated from each other and mix into the water. The water is polar, so it dissolves the polar color and sugar. The alcohol has a polar area but a larger ...
Because surfactants combine both polar and non-polar groups into a single molecule, they have the ability to adsorb (or locate) at interfaces, thereby altering significantly the physical properties of ...
