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.
Aromatic
Relates to organic compounds containing one or more planar ring structures with delocalized π-electrons, exhibiting unique stability and reactions.
