Sp3 hybrid orbitals

Definition

sp3 hybrid orbitals are formed when one s orbital and three p orbitals mix to create four equivalent orbitals. These orbitals have a tetrahedral geometry with bond angles of approximately 109.5 degrees.

Hybridization:

The process by which atomic orbitals mix to form new, equivalent hybrid orbitals suitable for bonding.

Tetrahedral Geometry:

A molecular shape where a central atom is surrounded by four atoms or groups of atoms at the corners of a tetrahedron, typically associated with sp3 hybridization.

Bond Angle:

The angle formed between three atoms across at least two bonds; in sp3 hybridized molecules, this angle is about 109.5 degrees.
