Molecular geometry of ethyne.

Each individual hybrid orbital is a combination of multiple atomic orbitals and has different s and p character affecting their shape, length, and acidic properties. An sp3 hybrid orbital is composed of four atomic orbitals, one s and three p, so the s character is ¼ or 25% (making the p character ¾ or 75%).Corresponding angles are easy to find once you know what to look for.

Electron-pair Geometry versus Molecular Structure. It is important to note that electron-pair geometry around a central atom is not the same thing as its molecular structure. The electron-pair geometries shown in (Figure 2.6.3) describe all regions where electrons are located, bonds as well as lone pairs. Molecular structure describes the location of the atoms, not the electrons.Bonding in Ethane. In the ethane molecule, the bonding picture according to valence orbital theory is very similar to that of methane.
