This page explains the hybridization of carbon atoms in molecules with double and triple bonds, using ethene (\ (\ce {C2H4}\)) and ethyne (\ (\ce {C2H2}\)) as examples.

Sigma bond, represented by the Greek symbol σ, is formed by head-to-head overlapping of atomic orbitals along the internuclear axis. The electron density is concentrated between the nuclei of the …

Sigma bonds are the strongest type of covalent bonds due to the direct overlap of orbitals, and the electrons in these bonds are sometimes referred to as sigma electrons.

Now, there are two types of covalent bonds: sigma (σ) and pi (π) bonds. The bonds that form by the head-on overlap of orbitals are called σ (sigma) bonds because the electron density is concentrated …

In this tutorial, we’ll look at the sigma and pi bonds in organic molecules. We’ll begin by reviewing the difference between ionic and covalent bonds, then look closer at how covalent bonds—specifically …

Jun 23, 2025 · Understand sigma and pi bonds in IB Chemistry. Compare orbital overlap, bond strength, and hybridisation in different molecules.

Jul 23, 2025 · Sigma bonds are characterized by their head-on overlap, greater electron density along the bond axis, and the ability to rotate freely. Pi bonds, on the other hand, involve parallel p-orbital …

Sigma bonds form when the available orbital with the highest energy of each atom overlaps one another. The constructive interaction will thus lead to the formation of a sigma bond between the two atoms …

Sigma bonds (σ) (σ) are the strongest type of covalent bond, formed by head-on overlapping of atomic orbitals. Note that sigma bond has been referred to as the strongest type of covalent bond because …

Aug 5, 2025 · Sigma bonds are fundamental to all chemical bonds. Every single bond between two atoms is a sigma bond. A single bond consists of one sigma bond. Because sigma bonds represent …
