Nonpolar and polar

Postby Jessica Tejero 3L » Sat Dec 07, 2019 12:01 pm

Whats the easiest ways to tell whether a molecule is polar or non-polar?

You should see if the dipoles cancel out in the molecule. If they cancel, then it's nonpolar and if they don't then it's polar.

I believe it is based on the electronegativity of the molecules

If the difference in electronegativity for the atoms in a bond is greater than 0.4, the bond is considered. If the difference in electronegativity is less than 0.4, the bond is essentially nonpolar. Sometimes you can tell from drawing out the molecule and looking at the charges and if its evenly spread out.
