Final answer:

Hybridization of the central atom in molecules is dependent on the number of electron density regions, with sp² hybridization for three regions in a trigonal planar geometry and sp³ for four regions in a tetrahedral geometry. Other hybridizations, such as sp and sp³d, occur with variations in bonding and lone pairs.

Step-by-step explanation:

Understanding the hybridization of the central atom in a molecule helps to describe the molecule's geometry and bonding properties. When a central atom is surrounded by three regions of electron density, it will exhibit sp² hybridization, resulting in three hybrid orbitals and one unhybridized p orbital oriented in a trigonal planar geometry. Conversely, a central atom surrounded by four regions of electron density will show sp³ hybridization, resulting in four hybrid orbitals in a tetrahedral geometry. If there is a mix of single, double, or triple bonds, or lone pairs, the hybridization can vary between sp, sp², sp³, and sp³d, depending on the combination of regions of electron density around the central atom.
