Adolf von Baeyer

Adolf von Baeyer (1835–1917) was a German chemist whose research on organic dyes and hydroaromatic compounds earned the 1905 Nobel Prize in Chemistry. He synthesized indigo and developed influential ideas about molecular structure.

August Kekulé: A German chemist who developed influential structural theories of organic molecules, including the ring structure of benzene. Baeyer studied with Kekulé, whose structural ideas shaped Baeyer’s approach to organic chemistry.
Indigo: A deep-blue dye and pigment historically obtained from plants and now produced mainly by chemical synthesis. Baeyer’s long campaign to determine its structure culminated in laboratory synthesis.
Structural formula: A representation of a molecule that shows how its atoms are connected and, in some forms, arranged. Baeyer used structural formulas to reason about the architectures of dyes and cyclic compounds.
Baeyer strain theory: A model that attributes the instability of small cycloalkanes to deviations from the preferred tetrahedral bond angle of carbon. Baeyer proposed this theory to account for the relative stability of carbon rings.
Organic chemistry: The branch of chemistry concerned primarily with carbon compounds, their structures, properties, and reactions. Baeyer’s work helped shape modern research on organic structure and synthesis.
Friedrich Wöhler: A German chemist whose synthesis of urea helped establish that organic compounds could be made from inorganic substances. Baeyer completed doctoral research under Wöhler at the University of Berlin.
Indigo synthesis: The chemical preparation of indigo from simpler compounds through a sequence of reactions. Baeyer devised routes that established indigo’s structure and enabled later industrial production.
Benzene: An aromatic hydrocarbon with molecular formula C₆H₆ and a six-carbon ring. Its unusual stability challenged structural models that Baeyer’s theories sought to clarify.
Ring strain: The energetic destabilization of a cyclic molecule caused by unfavorable bond angles, torsions, or steric interactions. The theory named for Baeyer is an early explanation of this molecular effect.
Chemical structure theory: The framework that describes molecules through defined atomic connections and chemical bonds. Baeyer applied structural reasoning to explain compounds whose formulas alone revealed little.
