Figure 9. The process of sp 2 hybridization is the mixing of an s orbital with a set of two p orbitals (p x and p y ) to form a set of three sp 2 hybrid orbitals. A mixing of the 2s-orbital with two of the 2p orbitals gives three sp 2 hybrid orbitals, leaving one of the p-orbitals unused. Two sp 2 hybridized carbon atoms are then joined together by sigma and pi-bonds (a double bond), as shown in part B. The single 2s orbital is spherical, different from the dumbbell-shaped 2p orbitals. This would indicate that one of the four bonds differs from the other three, but scientific tests have proven that all four bonds have equal length and energy; this is due to the hybridization of carbon’s 2s and 2p valence orbitals.

Thus the 2p orbitals for O, F, and Ne are higher in energy than the 2p orbitals for Li, Be, B, C, and N. Because of this, O 2 , F 2 , and N 2 only have negligible s-p mixing (not sufficient to change the energy ordering), and their MO diagrams follow the normal pattern, as shown in Figure 12.

2s 2p mixing

The observable fraction of 2p/sub 1/2/, 2s/sub 1/2/ and 2p/sub 3/2/ quantum state in the resulting coherent mixture is calculated. The amplitude of the oscillations, which appear when the field parameters are varied, is shown to depend only on the rate of change of the field, as seen by the atom. A mixing of the 2s-orbital with two of the 2p orbitals gives three sp 2 hybrid orbitals, leaving one of the p-orbitals unused. Two sp 2 hybridized carbon atoms are then joined together by sigma and pi-bonds (a double bond), as shown in part B. overlap of 2p orbitals is above and below, if in the plane of our paper, or in front and in back, if perpendicular to the plane of our paper. The picture of two interacting 2p orbitals looks something like the following.

This would indicate that one of the four bonds differs from the other three, but scientific tests have proven that all four bonds have equal length and energy; this is due to the hybridization of carbon’s 2s and 2p valence orbitals. In N 2 and in most other diatomic molecules (NO, NS, CO, CS) there are 4 sigma symmetry molecular orbitals made from a mixing of the 2s and 2p z atomic orbitals on each atom. In both molecules the pi symmetry molecular orbitals are the same. In order for 4 hydrogens to bind there need to be 4 electrons available for bonding, which cannot be achieved at the moment. The pull of a hydrogen nucleus results in an electron being excited from the 2s subshell into the 2p subshell, where it is available for bonding.
