Exceptions for Polarity

Postby alex_4C » Sun Nov 03, 2019 10:58 pm

Here's some rules for polarity and exceptions of when it's non-polar. Hope this helps!
Everything can be considered a polar bond except for two instances
1) carbon and hydrogen bond (not polar mostly just equal sharing of electrons)
2) atom bonded to the identical atom (no difference in electronegativity, purely covalent)

Thank you for this tip! Does anyone have any similar tips for determining if a molecule is polar without being given the electronegativity values for atoms? Also, will we be provided with these values on the midterm?
