sp3 hybridized is a term used in chemistry to describe the type of atomic orbital hybridization that occurs when one s atomic orbital and three p atomic orbitals mix to form four new, equivalent sp3 hybrid orbitals. This process is fundamental to understanding the bonding and molecular geometry of many organic and inorganic compounds.

In a typical sp3 hybridization scenario, a central atom, such as carbon, undergoes a transformation where its valence electrons rearrange. The original s orbital, which is spherical, combines with the three p orbitals, which have dumbbell shapes along the x, y, and z axes. The result of this mixing is the creation of four sp3 hybrid orbitals that are directed towards the corners of a tetrahedron. These orbitals are equivalent in energy and shape, and their spatial arrangement dictates the geometry around the atom.

The most common example of sp3 hybridization is seen in saturated hydrocarbons, like methane (CH4). The carbon atom in methane is sp3 hybridized, forming single covalent bonds with four hydrogen atoms. The tetrahedral geometry resulting from sp3 hybridization allows for the maximum separation of electron pairs, minimizing repulsion and leading to a stable molecular structure. This hybridization is also prevalent in molecules like ammonia (NH3) and water (H2O), where the central atom is sp3 hybridized, though the presence of lone pairs influences the overall molecular geometry (trigonal pyramidal for ammonia, bent for water). The concept of sp3 hybridization is crucial for predicting bond angles, molecular shapes, and chemical reactivity.
