VSEPR

[Brett Lieuallen 2A]

Can the VESPR model be used to determine polarity?

[Alen Huang 2G]

Yes I believe so! The symmetry of the structure is important in determining whether the whole molecule is polar or not because two polar bonds can cancel each other out if they are opposite of each other and create a nonpolar molecule overall.

[Jordan Tatang 3L]

Yup! Like Alen said the VSEPR model shows you if the molecule is symmetrical or asymmetrical and therefore non-polar or polar, respectively.

[Shrinidhy Srinivas 3L]

Yes! The VSEPR model helps show the shape and structure and by doing so, shows you the polarity of the model. One of the examples was the octahedral model that Lavelle talked about in lecture today!

[Sabine Salvucci 2E]

Yep! The VSEPR model helps show the 3D shape of the molecule and therefore whether a molecule is symmetrical or asymmetrical. The symmetry of a molecule is directly related to its polarity, with symmetrical molecules being non polar and asymmetrical molecules being polar. Hope this helps!

[Jiapeng Han 1C]

Actually molecular shape is one very effective way to determine polarity. Typically, symmetrical molecule is non-polar while non-symmetrical molecule is polar because the dipoles can't cancel out.

[Lizbeth Garcia 1F]

Yes, the VSEPR model helps determine the shape and structure of a molecule which then helps determine polarity.

[Juliet Carr 1F]

It is really important to consider VSEPR when determining polarity because VSEPR will show symmetry in the shape of the molecule. So, if there are unequal pulls on the central atom in different directions by the dipole moments surrounding it, then the dipole moments cannot cancel and the molecule is polar.

[Shalyn Kelly 3H]

Hi! As those above have stated: yes, VSEPR helps determine the polarity of a molecule because the theory is that electron pairs and lone pairs repel each other, thus making a more symmetrical shape for the molecule (non-polar) vs. having awkward pulls and skewing the shape making the molecule polar.
Take CO2 where the molecule's shape is linear because the two O bits are repelling each other and trying to stay as far away from each other as possible, making the molecule symmetrical.

[Abraham De Luna]

Yes, I believe that it can help determine polarity because because VSPER helps determine the shape and structure of the molecule.

[Madeline Marron 1I]

yes! the VSEPR model can be used to measure polarity
