sigma bond

Postby Kyle Thorin » Mon Nov 18, 2019 1:55 pm

What is a sigma bond, and what does the s-s overlap, s-p overlap, and p-p overlap mean?

A sigma bond is a bond that forms when one electron from each of the two orbitals with interacts end-to-end. Overlapping just means it's in phase, or the orbitals are sharing the same space.

The overlaps are referring to their electron in the orbitals overlapping making them shared

Sigma bonds occurs when two orbitals interact/overlap end-to-end, which typically leads to them having one region of shared electron density. Imagine a venn diagram where the two circles are the orbitals of two atoms and the overlapping region is the region of shared electron density. This middle shared region is the sigma bond. The s-s, s-p, and p-p overlap indicates which orbitals between the two atoms are interacting with each other to create this shared region of electron density.

A sigma bond means that the orbitals overlap end to end. Sigma bonds also allow for rotation.

A sigma bond is a bond between two orbitals (s and s, s and p, etc) where they overlap end to end and can rotate.

Sigma bonds are first to form between atoms. They are formed by atomic orbital overlap and they allow for rotation.

A sigma bond is just an area of two orbitals overlapping creating a significant area of electron density.
