Viscinal Dihalide

A type of dihalide compound where two halogen atoms are attached to adjacent carbon atoms in an organic molecule.

Degenerate Orbitals

Orbitals that have the same energy level but differ in orientation in space, often found in subshells of atoms.

π Molecular Orbitals

Orbitals formed by the overlap of p orbitals on adjacent atoms, allowing for the delocalization of electrons over several atoms in a molecule.

Substituted Cyclobutadiene
