What you can learn
- A bond is polar when the two atoms differ in electronegativity.
- Bond dipoles are vectors: they can cancel out in a symmetric molecule like CO₂.
- A bent molecule such as H₂O does not cancel, so it is polar.
Frequently asked questions
How can a molecule with polar bonds be nonpolar?
If the shape is symmetric, the bond dipoles point in opposite directions and cancel, as in linear CO₂.
What is electronegativity?
How strongly an atom pulls shared electrons toward itself. The more electronegative atom gets the partial negative charge.
