Which non-covalent interaction is stronger - ResearchGate

WebThe overlap of two s orbitals (as in H2), the overlap of an s orbital and a p orbital (as in HCl), and the end-to-end overlap of two p orbitals (as in Cl2) all produce sigma bonds (σ bonds), as illustrated in Figure 21.3.A σ bond is a covalent bond in which the electron density is concentrated in the region along the internuclear axis; that is, a line between the nuclei … WebKinds of covalent bonds (occur between atoms in a molecule) Which is stronger and why? Sigma bonds are stronger due to end to end overlap which gives the molecule flexibility around the axis. Which is weaker and why? Pi bonds are weaker due to the sideways overlap which requires the molecule to stay rigid, making them easier to break.
