Sigma vs. Pi

Postby Lelija Kazlauskas 3J » Sun Dec 01, 2019 10:36 pm

Theoretically, would a single sigma bond or a single pi bond be stronger?

Sigma bonds are stronger because the two orbitals overlap, as opposed to a pi bond where the two orbitals are side by side.

Sigma bonds are bonded to a greater extent because the orbitals are overlapping each other. This increased surface area of the bond makes it stronger than the side to side pi bonds.

Sigma bonds are stronger due to the orbital overlap.

sigma bonds will be stronger since its an overlap

Sigma bonds would be stronger because of the overlapping orbitals while pi bonds don't have this overlap.

sigma bonds would be stronger because there is overlap in their orbitals

Sigma bonds are significantly stronger than pi bonds because of an overlap in orbitals.

Because of the overlap, sigma bonds are stronger. They are also more flexible, where pi bonds are more rigid.

Sigma bonds are stronger than pi bonds because if you look at the 3D diagram of the orbitals, the heads of the two p orbitals in a sigma bond overlap, where as a pi bond is simply the attraction of two parallel p orbitals. This overlap is why sigma bonds are stronger.

Are pi bonds weaker, because they stop the molecule from rotating and require a higher boiling point to be broken?

Sigma bonds are stronger and this makes sense because if the molecule rotates pi bonds will be broken.

This response is correct as the overlapping of two P orbitals causes the stronger force.

Sigma bonds are stronger because the orbitals overlap whereas for pi bonds, the orbitals can break when the molecule rotates.
