See Below


Molecules are generally hydrophobic if they don't have polar bonds, ionic regions, or hydrogen bond donors and acceptors.

Oil, gasoline, vegetable oil - these things have long carbon chains with many hydrogens. But C-C bonds and C-H bonds are nonpolar, and so they don't generally like to interact with polar bonds (like O-H bond in water).
