"WebApr 9, 2024 · The covalent bond formed by the axial overlap of atomic orbitals is called a sigma bond. For example, the methane molecule contains 4 C-H sigma bonds. This type of covalent bond is formed by the overlap of bonding orbitals along the internuclear axis from end to end (head-on). This is called head overlapping or axial overlapping.

WebElectron density is zero along the axis of the molecule (i.e., the internuclear axis). iii. In the formation of a sigma bond, the extent of overlap is greater, hence, more energy is released. In the formation of a pi bond, the extent of overlap is less, hence, less energy is released. iv.
