Use Lagrange multipliers to find the closest point on the given curve to the indicated point.
Antiaromatic
Compounds that possess conjugated pi electrons in cyclic structures but with destabilization due to unfulfilled criteria for aromatic stability.
Nonaromatic
Describes a compound that does not meet the criteria for aromaticity, lacking a cyclic, planar structure with a delocalized pi electron system over the ring.
Pyrene
A polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings, resulting in a flat aromatic system.
Huckel Rule
A rule that helps predict the aromaticity of planar rings based on the count of pi electrons, stating that aromatic compounds must have 4n+2 pi electrons.
