Hydrophilic and hydrophobic molecules are also known as polar molecules and nonpolar molecules, respectively. The isopropyl and methyl groups are responsible for solvation in nonpolar solvents. Pentanes are miscible with most common nonpolar solvents such as chlorocarbons, aromatics, and ethers. Waxes are insoluble in water but soluble in organic, nonpolar solvents. Oil is any of a number of nonpolar, hydrophobic, and viscous liquids. It is soluble in nonpolar organic solvents. Titanium isopropoxide is mainly a monomer in nonpolar solvents. Detergents and surfactants are molecules that combine highly nonpolar and highly polar groups. Conic phases, except nonpolar nematic, are polar phases. It is practically insoluble in water, but readily soluble in nonpolar organic solvents. Unlike the halides, the alkoxides dissolve in nonpolar solvents. This colorless solid is soluble in nonpolar organic solvents and not in water. Like most such compounds, it is highly soluble in nonpolar organic solvents. Lipases can also digest lipids that form micelles or nonpolar droplets in water. Since the salt is poorly soluble in nonpolar solvents, crown ethers are typically used.
