WebApr 9, 2024 · Both names, sigma and pi, are derived from the Greek letters. Various bond properties, including bond length, bond angle, and bond enthalpy, are influenced by how atomic orbitals overlap. This overlap happens in two ways, resulting in two different types of covalent bonds: sigma and pi bonds. Generally, sigma bonds are stronger than pi bonds. WebSigma bonds are known to have cylindrical charge symmetry around the axis of the bond. No symmetry exists in pi bonds. Atoms with sigma bonds are less reactive. Atoms with pi bonds are highly reactive when compared to those with only sigma bonds. Sigma bond can be used to determine the shapes of molecules.

"WebCylindrical symmetry means that if you draw a line along the internuclear axis, then the bond is everywhere symmetric about this line. A sigma bond possess this because it is invariant under rotation about this axis. That is to say, if you rotate molecules with a sigma bond about this axis, nothing about the bond changes.
