Sigma vs. Pi

[Lelija Kazlauskas 3J]

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

[zachary_nhem_4I]

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

[TYun_1C]

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.

[Jacob Villar 2C]

Sigma bonds are stronger due to the orbital overlap.

[JohannaPerezH2F]

sigma bonds will be stronger since its an overlap

[kendal mccarthy]

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

[pJimenez3F]

Sigma bonds are stronger due to the orbitals overlapping

[san_2F]

sigma bonds would be stronger

[ShravanPatel2B]

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

[VioletKo3F]

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

[HanaAwad_4B]

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

[SVajragiri_1C]

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.

[AnayaArnold_3L]

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

[serenabirkhoff_1K]

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

[Alan Cornejo 1a]

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

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

[Annie Ye]

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

[Xavier Herrera 3H]

Sigma bonds are stronger because they occur for single bonds or the first bond between atoms, allowing the orbitals to overlap on their ends and giving enough flexibility for the bond to rotate when the molecule rotates. Pi bonds occur on the second or third bond, so their orbitals overlap side to side, preventing the molecule from rotating without the bond breaking.

[Jasraj Parmar 3H]

Sigma bonds are stronger because they allow for electron density to be more concentrated between the two nuclei. A pi bond also has a weaker covalent bond than a sigma bond.

[Katelyn_Ortega_1D]

Sigma is stronger than Pi bonds

[Keshav Patel 14B 2B]

Sigma bonds are much stronger because when they overlap each other, they have a higher strength. While Pi bonds are side by side thus having less connection and much less strength.

[Ariel Guan 1H]

Sigma bonds are stronger because they overlap!
