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. Alcohol molecules do not attract each other as strongly as water molecules and ...

Students investigate the polarity of the water molecule and design tests to compare water to less polar liquids for evaporation rate, surface tension, and ability to dissolve certain substances.

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...

The non-polar tail of the molecule can be called hydrophobic as it is repelled by water. However, the polar, ionic head is hydrophilic and does dissolve in polar solvents such as water.
