Determining polarity from VSPER

Postby Ashley Osorio » Fri Dec 06, 2019 1:03 am

How can we determine the polarity just from the VSPER formula?? Pls explain

you can't tell polarity just from the VSEPR formula. You need the VSEPR model to tell the shape.

You can use VSEPR to determine the shape, some of which can more easily lead to polarization than others. In general, though, you need to know the electronegativity of the atoms.

VSEPR is used to determine the shape and once you have the shape, you can determine the polarity from there!

The VSEPR shape would be a better indication of polarity, a little trick to remember is that lone pairs will make a molecule polar, but it is always a good idea to draw the shape
