VSEPR and Polarity

[Sumaiyah I 1E]

How does VSEPR shape/structure help determine polarity?

[Manuel Gonzalez_1L]

You first draw the lewis dot structure of the compound. Then see where there are any lone pairs. If there are lone pairs and others have bonds then it is polar but if it's all equal and as they pull, they cancel each other out then it is non-polar.

I think that knowing the shape a molecule takes and how it looks helps visually determine whether the molecule is polar or nonpolar unlike the lewis structure which shows the basic design of what atom is bonding where and how many lone pairs are present. The VSEPR model helps you actually see a better picture.
