Bond Angle

Postby Catherine Bubser 2C » Fri Nov 20, 2020 7:06 pm

What was the angle measurement for the 'seesaw' molecular shape? Will this differ based on the exact atoms in the molecule?

Online it says the angle measurement for the 'seesaw' molecular shape is between 90 and 120 degrees but I'm not sure about the second question. I think it might not depend on the exact atoms in the molecule since its more about the shape, but I'm not sure that is correct. I hope that helps!

Yes, I think all molecular shape bond angles can differ slightly from what is expected based on what atoms are in it. For example, SF4 has a see-saw geometry but has bond angles of 173 degrees and 102 degrees.

I think the bond angle depends on the exact atoms in the molecules. We can get the actual values through experiments data.

Yes I believe the bond angle can differ based on the electronegativity of the atoms involved

Yes, I think it will differ based on the exact atoms involved. This is because of the difference in the electronegativity of the atoms involved in bonding

Bonds differ on the atoms yeah. Lavelle says we're not expected to get the exact measure and are unable to with the VSEPR model because it predicts distortions qualitatively not qaunt. Different electronegativities are present with different atoms so the angles vary.

Yes it differs, depending on what atoms are present in the molecule.

Bond angles will depend on what molecule you are examining.

Bond angles are dependent on which atoms are in the molecule. Since the VSPEPR model predicts qualitatively and not quantitively, we are unable to figure out the exact measure.
