Sigma and Pi Bonds affect on structure

Postby juleschang16 » Fri Nov 16, 2018 6:27 pm

Do the number of sigma and pi bonds influence the shape/structure of a molecule? How so?

The number of sigma and pi bonds don't influence the shape or structure of a molecule. This is because when determining the molecular shape, instead of the number of bonds we look at the electron regions as a single charged region.

Sigma and Pi bonds do not affect structure. The only things that impact the structure is the lone pairs and bonds

Sigma and Pi bonds do not affect the shape or structure because in VSEPR, all bonds are treated as equivalent. Single, double, and triple bonds are all considered one region of electron density. Though Sigma and Pi bonds impact the movement and rotation of molecules. Molecules with only sigma bonds are able to rotate. But, once a pi bond is added, the molecule becomes more essentially locked and cannot rotate.

Sigma and Pi bonds don't affect the structure. However, the lone pairs and amount of bonds do.
