polar bonds and molecular shape

Postby sarahsalama2E » Mon Nov 11, 2019 2:40 pm

I know we haven't covered this yet, but just wondering how exactly polar bonds affect the shape of a molecule?

Polar bonds do not affect molecular shape. However, molecular shape does affect the polarity of a molecule when there are polar bonds. Since we can think of dipole moments as vectors, if they do not cancel based on the shape of the molecule, then the molecule will be polar. If they do cancel, then the molecule will be nonpolar even though there are polar bonds.

In high school, my class learned that molecules with an uneven electron distribution, like water, are polar, while molecules with a more even electron distribution, such as methane, are considered to be non-polar.
