Its is possible for a molecule to have a polar bond but have an overall polarity of nonpolar?

A molecule can possess polar bonds and still be nonpolar. If the polar bonds are evenly (or symmetrically) distributed, the bond dipoles cancel and do not create a molecular dipole. For example, the three bonds in a molecule of BF3 are significantly polar, but they are symmetrically arranged around the central boron atom. No side of the molecule has more negative or positive charge than another side.

Because it was a dramatically big guy

Ineed with this also i hope you understand it
