Lacking any affinity or attraction to [[water]].  The ability to repel water from one's molecular structure.

'''Hydrophobic''' describes [[molecule]]s which lack any affinity or attraction to [[water]].

This is caused by the polarity of water molecules due to the electron affinity of the oxygen atom.  Hydrophobic molecules tend to be neutral and non polar, and avoid contact with polar molecules, like water. If immersed in water, hydrophobic molecules will clump together to decrease the total surface area that is in contact with the water.

Hydrophobic molecules tend to be electronically neutral and [[nonpolar]]. If immersed in water, hydrophobic molecules will coalesce together to decrease the total [[surface area]] in contact with the water.

Prominent examples of hydrophobic molecules are oils and fats, these are in addition to alkanes. Any greasy substance usually will also be hydrophobic.

Prominent examples of hydrophobic molecules include oils and fats, as well as any nonpolar [[organic]] molecules. Any greasy substance usually will also be hydrophobic.
