What type of molecules are "water fearing" and try to stay away from water or other polar molecules?

Answer 1

#"Hydrophobe"="water fearer"#

And hydrophobic molecules include the alkanes, #C_nH_(2n+2)#, the alkenes and alkynes, alkyl halides, oils, fats....

As the hydrocarbyl tail gets bigger, even molecules with polar groups, like alcohols, have less water solubility.
