Final answer:
It is false that molecules with identical bonds are always nonpolar; molecular geometry plays a key role in determining the overall polarity.
Step-by-step explanation:
The statement that any molecule in which all of the bonds are identical will be nonpolar is false. A molecule may contain bonds that are identical in polarity, and yet it can be polar or nonpolar depending on its molecular geometry.
When a molecule has high symmetry, such as tetrahedral (CH4) or trigonal planar (BF3) geometries, the polarity vectors of the individual bonds cancel out, resulting in a nonpolar molecule.
On the other hand, molecules with less symmetry like H2S and NH3 can have identical polar bonds but due to the molecular shape, they do not cancel each other out, which makes these molecules polar.
