Energy changes occurring in hybridization. Hybridization of an s orbital with two p orbitals (p x and p y) results in three sp 2 hybrid orbitals that are oriented at 120 o angle to each other (Figure 3). Sp 2 hybridization results in trigonal geometry.
Use the one that best explains the geometry. For oxygen, assume at least one unhybridised p-orbital. For a nitrogen with three single bonds, remember that the hybridisation will always switch between sp3 s p 3 and sp2 + p s p 2 + p. This is the nitrogen inversion. Hydrogen needs no hybridisation.
The formation of hybrid atomic orbitals can be viewed as occurring via promotion of an electron from a filled ns 2 subshell to an empty np or (n − 1)d valence orbital, followed by hybridization, the combination of the orbitals to give a new set of (usually) equivalent orbitals that are oriented properly to form bonds.
In chemistry, orbital hybridisation (or hybridization) is the concept of mixing atomic orbitals to form new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) suitable for the pairing of electrons to form chemical bonds in valence bond theory.
When only one p orbital participates in hybridization, the result is two sp hybrid orbitals and a linear orbital geometry. The two remaining p orbitals are available for pi-bonding (as in triply-bonded organic compounds such as alkynes and nitriles) or can be empty (as in BeCl 2).
Hybridisation and geometry of molecules play a vital role in their reactivity. Reactions involve making and breaking of "bonds"! So, before we start with organic chemistry, let's revise a few things about bonding in organic molecules.
Hybridisation (or hybridization) is a process of mathematically combining two or more atomic orbitals from the same atom to form an entirely new orbital different from its components and hence being called as a hybrid orbital.
