Hybridizationin Chemistry, is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals. This intermixing usually results in the formation of hybrid orbitals having entirely different energy, shapes, etc. The atomic orbitals of the same energy level mainly take part in hybridization. However, both fully-filled and half-filled orbitals can also take part in this process, provided they have equal energy.

Let us have a quick look at the example of a carbon atom. This atom forms 4 single bonds wherein the valence-shell s orbital mixes with 3 valence-shell p orbitals. This combination leads to the formation of 4 equivalent sp3 mixtures. They will have a tetrahedral arrangement around the carbon, which is bonded to 4 different atoms.

Based on the types of orbitals involved in mixing, the hybridization can be classified as sp3, sp2, sp, sp3d, sp3d2 and sp3d3. Let us now discuss the various types of hybridization, along with their examples.

sp hybridization is observed when one s and one p orbital in the same main shell of an atom mix to form two new equivalent orbitals. The new orbitals formed are called sp hybridized orbitals. It forms linear molecules with an angle of 180.

sp2 hybridization is observed when one s and two p orbitals of the same shell of an atom mix to form 3 equivalent orbitals. The new orbitals formed are called sp2 hybrid orbitals.

Due to the spherical shape of the s orbital, it is attracted evenly by the nucleus from all directions. Therefore, a hybrid orbital with more s-character will be closer to the nucleus, and thus more electronegative. Hence, the sp hybridized carbon is more electronegative than sp2 and sp3.

During hybridization, the hybrid orbitals possess different geometry of orbital arrangement and energies than the standard atomic orbitals. Also, the orbital overlap minimises the energy of the molecule. The degenerate hybrid orbitals formed from the standard atomic orbitals are as listed:

The sp hybridization occurs due to the mixing of one s and one p atomic orbital, the sp2 hybridization is the mixing of one s and two p atomic orbitals, and the sp3 hybridization is the mixing of one s and three p atomic orbitals.

The 2s and all the three (3p) orbitals of carbon hybridize to form four sp3 orbitals. These hybrid orbitals bond with four atoms of hydrogen through sp3-s orbital overlap resulting in CH4 (methane). The geometry of orbital arrangement due to the minimum electron repulsion is tetrahedral.

The general process of hybridization will change if the atom is either enclosed by two or more p orbitals or it has a lone pair to jump into a p orbital. Therefore, in the case of an amide molecule, the lone pair goes into a p orbital to have 3 adjacent parallel p orbitals (conjugation).

In the last few posts, we studied about the most common types of hybridization namely -sp3, sp2, and sp hybridization. These are exhibited predominantly by elements in the second period of the periodic table(e.g. Carbon, Oxygen, Nitrogen, Beryllium, etc).

However, the concept of hybridization can be extended to the p- block elements(e.g.- Suphur, Phosphorous, Iodine etc ) as well.The p-block elements have vacant d-orbitals of similar energy (NOT SAME) , as that of valence s- and p-orbitals. Thus, the electrons from the s-orbital can be excited to the vacant d-orbitals. Then the s, p and d orbitals mix to form sp3d, sp3d2 or sp3d3 hybrid orbitals.These type of hybridizations are different than the earlier ones as they involve the vacant d-orbitals.

thanks for your reply. but my concern is that is that possible to convert revit file to sp3d file. is the cadexchanger mediator tool between revit and sp3d? Your ellaboration will be highly appeciatable.

Sigma (σ) Bonds form between the two nuclei as shown above with the majority of the electron density forming in a straight line between the two nuclei. I often refer to this as a "head-to-head" bond.

For sp2 hybridized central atoms the only possible molecular geometry is trigonal planar. If all the bonds are in place the shape is also trigonal planar. If there are only two bonds and one lone pair of electrons holding the place where a bond would be then the shape becomes bent.

For sp3 hybridized central atoms the only possible molecular geometry is tetrahedral. If all the bonds are in place the shape is also tetrahedral. If there are only three bonds and one lone pair of electrons holding the place where a bond would be then the shape becomes trigonal pyramidal, 2 bonds and 2 lone pairs the shape is bent.

For sp3d hybridized central atoms the only possible molecular geometry is trigonal bipyramidal. If all the bonds are in place the shape is also trigonal bipyramidal. If there are only four bonds and one lone pair of electrons holding the place where a bond would be then the shape becomes see-saw, 3 bonds and 2 lone pairs the shape is T-shaped, any fewer bonds the shape is then linear.

For sp3d2 hybridized central atoms the only possible molecular geometry is Octahedral. If all the bonds are in place the shape is also Octahedral. If there are only five bonds and one lone pair of electrons holding the place where a bond would be then the shape becomes Square pyramid, 4 bonds and 2 lone pairs the shape is square planar, 3 bonds and 3 lone pairs the shape is T-shaped. Any fewer bonds the shape is then linear:
