Rotation

Postby Daniel Hernandez 1G » Sun Nov 29, 2020 8:32 pm

If an area of electron density contains a pi bond, is it safe to assume that there are at least two bonds present in the particular area?

Yes I would say that that makes sense

Yes, a pi bond can only happen when there is a double or triple bond present between two atoms. Likewise, if there is only a single bond, then you can assume that the bond is a sigma bond.

A single bond is a sigma bond. A double bond is a sigma and a pi bond. A triple bond is a sigma and two pi bonds.

Yes because Pi bonds are only seen in double and triple bonds, where a double bond has 1 pi bond and a triple bond has 2 pi bonds.

Yes. A sigma bond is present in a single bond while a double bond has a sigma and pi bond. A triple bond has a sigma and two pi bonds.

Yes, for a pi bond to be present there must be multiple bonds between two atoms.

If a a pi bond is present that means that a sigma bond is also present.

If there is a pi bond, then a sigma bond must be present. I believe there is always a pi bond and sigma bond when there is a double bond or more than a double bond present. Correct me if I'm wrong.

Write it in a straightforward way:

single bond = sigma-bond
double bond = sigma-bond + pi-bond
triple bond = sigma-bond + 2 pi-bonds

Yes, I think so. A single bond only contains sigma bond; a double bond has one sigma and one pi bond. A triple bond has a sigma and two pi bonds.

Yes, if there is a pi bond present, there will at least a double bond or bond with greater strength present.

Yes that would make the most sense.

Yes, as long as you know there is one pi bond and not just pi bonds then I think it is safe to assume its at least a double bond.
