Just to echo what other people have said on this thread, if a nonpolar molecule has a more flat shape, the molecules can get closer together and tough with a higher amount of surface area. This means that the London forces will be larger. When dealing with polar bonds, the molecular shape is also important. Bonds themselves can be polar, but just because bonds are polar, that does not necessarily mean that the molecule itself is polar. For example, in CO2, the CO bond is polar, but since the molecular shape is a line, the polar vector dipoles cancel each other out, causing the molecule to be nonpolar (even though it contains polar bonds). I hope that helps!
