Double/Triple Bonds

[Ahmet_Dikyurt_3L]

Do double or triple bonds affect the shape or bond angles? I know that they are treated the same electron density, but does the angles change even a little?

[Aidan Ryan 1B]

In reality I think that they do force the other bonds away b/c there are more e- in the area but we haven't talked about this in class so I am not completely sure.

No they do not; they are treated as single electron density therefore can repulse only as much. Angles change from the influence of lone pairs which has a larger repulsion since they take up more space than bonded atoms. Knowing that atoms are bonded with either double or triple bonds only help formulate the VSEPR model to determine if there are any lone pairs that influence its structure.

They do not change the bond angles, its the lone pairs which contribute mostly to that, however triple bonds are stronger than double or single bonds.

[Nathan Tran 4K]

Lavelle discussed in lecture that the number of bonds should not affect the regions of electron density. Thus, with the information we have now, it is best to assume that double and triple bonds do not affect shape. However, of course there may be nuances to this, but I think that we can stick to this assumption based off what we learned so far.

Double and triple bonds don't affect bond angles, but the lone pairs do.
