sp2orbitaaleja

sp2 orbitaaleja refers to a type of atomic orbital hybridization found in chemistry. This hybridization occurs when one s atomic orbital and two p atomic orbitals on the same atom combine to form three new, equivalent sp2 hybrid orbitals. These three sp2 orbitals are degenerate, meaning they have the same energy level. They are arranged in a trigonal planar geometry, with bond angles of approximately 120 degrees between them. The remaining unhybridized p atomic orbital is oriented perpendicular to the plane of the sp2 hybrid orbitals.

This type of hybridization is commonly observed in atoms that form double bonds, such as carbon atoms in alkenes. For example, in ethene (C2H4), each carbon atom is sp2 hybridized. The three sp2 hybrid orbitals on each carbon atom form sigma bonds with the other carbon atom and with two hydrogen atoms. The unhybridized p orbital on each carbon atom overlaps sideways with the unhybridized p orbital on the adjacent carbon atom to form a pi bond, which constitutes the second bond in the carbon-carbon double bond. This sp2 hybridization allows for the formation of planar molecular structures and is crucial for the stability and reactivity of many organic molecules.
