Given the lewis dot structure of a compond how do i tell if it's polor or nonpolar?

Answer 1

First, it's best not to depend on electron do structures for that. Not only do you have to look at electronegativity differences between central and peripheral atoms, but you have to gauge whether structures are symmetrical or not.

If there are single bonds to the same other atoms on all four "sides" of the Lewis structure, it is probably nonpolar owing to symmetry. If there are four single bonds, but they are to different elements, there may be polarity.

If there is one or two nonbonding (lone) pairs, there may be polarity, because of less symmetry.

Answer 2

it has more stars, lewis
