Why are Both Cooking Oil and Gasoline (A Hydrocarbon)considered Hydrophobic

Question

Why are both cooking oil and gasoline (a hydrocarbon)considered hydrophobic molecules?
A)Neither have a polar or charged region.
B)Neither have a nonpolar region.
C)Both have hydrophobic and hydrophilic regions.
D)Both are highly reduced molecules.
E)Both mix with water.

Accepted Answer

Hydrophobic molecules do not mix with water because they do not have a polar or charged region that can interact with the polar water molecules. Cooking oil and gasoline are hydrophobic molecules because they consist mostly of nonpolar hydrocarbon chains and lack a polar or charged region.
