Definitions:

Atomic Orbitals

Mathematical functions that describe the wave-like behavior of an electron in an atom, these orbitals determine the distribution of electrons around an atom’s nucleus.

Hybrid Atomic Orbitals

Orbitals formed by the combination of standard atomic orbitals within an atom, explaining the bonding and geometry of molecules more accurately than unhybridized orbitals.

C-O Bond

A chemical bond between carbon and oxygen atoms, common in various organic and inorganic molecules and materials.

IUPAC Name

A structured technique for the naming of chemical compounds suggested by the International Union of Pure and Applied Chemistry.
