π Molecular Orbitals

Orbitals formed by the overlap of p-orbitals across adjacent atoms, involved in pi bonding, crucial for the understanding of conjugated systems.

Occupied π Molecular Orbitals

π molecular orbitals that contain electrons; they are involved in bonding between atoms and are crucial for understanding the reactivity of molecules.

Cyclobutadiene

A highly unstable, conjugated diene with the molecular formula C4H4, characterized by a square planar structure that challenges classical bonding theories.

[4]annulene

A cyclic compound made up of four conjugated carbon atoms, known for its planar structure and aromatic behavior despite having 4 π-electrons, which does not follow Huckel's rule for aromatic stability.
