Explain the concept of hybridization and its role in molecular geometry.

Hybridization is the process in which atomic orbitals mix to form new hybrid orbitals, which are used to form covalent bonds in molecules. This concept helps explain the geometry of molecules in a more accurate way than just considering the atomic orbitals of individual atoms.

  • sp Hybridization: Occurs when one s orbital and one p orbital combine to form two sp hybrid orbitals. This type of hybridization leads to a linear molecular geometry. An example is beryllium chloride (BeCl₂).

  • sp² Hybridization: Occurs when one s orbital and two p orbitals combine to form three sp² hybrid orbitals. This type of hybridization leads to a trigonal planar molecular geometry. An example is boron trifluoride (BF₃).

  • sp³ Hybridization: Occurs when one s orbital and three p orbitals combine to form four sp³ hybrid orbitals. This type of hybridization leads to a tetrahedral molecular geometry. An example is methane (CH₄).

Hybridization plays a crucial role in determining the shape and bond angles in molecules, thus influencing their physical and chemical properties.
