Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals that can accommodate bonding. In the context of bond formation, it helps explain the geometry and bond angles in molecules. For example, sp² hybridization involves one s orbital and two p orbitals, resulting in three equivalent orbitals arranged in a trigonal planar shape, which is crucial for understanding the bonding in organic compounds.

Orbital overlap refers to the interaction of atomic orbitals from two atoms to form a chemical bond. The extent of overlap determines the strength of the bond; greater overlap leads to stronger bonds. In covalent bonding, an s orbital can overlap with another s or p orbital, while p orbitals can overlap with each other, forming sigma (σ) and pi (π) bonds, respectively, which are essential for understanding molecular structure.

In chemistry, bonds can be classified into sigma (σ) and pi (π) bonds. Sigma bonds are formed by the head-on overlap of orbitals, allowing for free rotation around the bond axis, while pi bonds result from the side-to-side overlap of p orbitals, restricting rotation. Understanding these types of bonds is crucial for analyzing molecular geometry and reactivity, particularly in complex organic molecules like Tagamet.
