Question
Which is true regarding bond and molecular polarity
If the molecule contains multiple polar bonds, the molecule may be nonpolar if the dipoles cancel.
Molecules that have polar bonds are always polar
If the difference in electronegativity is 0.5 or greater, the molecule must be polar
If the molecule contains multiple polar bonds, the molecule may be nonpolar if the dipoles don't cancel.

- Following is a molecule with polar bonds whose shape was obtained using the VSEPR theory. Specify the molecular shape of this molecule, and whether the molecule is polar or nonpolar. (Hint: In terms of polarity, see whether the dipoles in the molecule cancel or not. A molecule containing polar bonds can be nanpolar if the dipoles cancel each other. You can imagine the dipoles as ropes pulling on the central atom–If the pulls cancel each other, that is, the central atom cannot move, then the molecule is nonpolar. If on the other hand the opposite is true, then the molecule is polar.)
