Sigma bonds result from an overlap of sp 2 hybrid orbitals, whereas pi bonds emerge from tunneling between the protruding p z orbitals. For clarity, only a few neighboring p z orbitals are shown.

Welcome to week 3! This week includes introduction to the octet rule and expanded octets, formal chargevalence shell electron pair repulsion (VSEPR) theory, sigma and pi bonds, hybridization of the main group elements, and introduction to molecular shapes.

I hope you enjoyed the last two weeks of learning chemistry.

Dubbel kovalent bindning. Enkel-, dubbel- och trippelbindning

A sigma bond (σ bond) is a bond formed by the overlap of orbitals in an end-to-end fashion, with the electron density concentrated between the nuclei of the bonding atoms. A pi bond (π bond) is a bond formed by the overlap of orbitals in a side-by-side fashion with the electron density concentrated above and below the plane of the nuclei of the bonding atoms.

When two p orbitals overlap side-to-side, they form a π bond. s and p orbitals can form different hybridizations.
