Henry Taube

Alfred Werner

Erich Huckel

Emil Fischer

- Option 1: Henry Taube

- Known for work on electron transfer in metal complexes.

- Received the Nobel Prize in Chemistry in 1983.

- Taube's work emphasized mechanistic insights rather than coordination theories.

- Option 2: Alfred Werner

- First proposed the coordination theory of complex compounds in 1893.

- Suggested spatial arrangement of ligands around metal ions, introducing the idea of coordination numbers.

- Awarded the Nobel Prize in Chemistry in 1913 for his coordination chemistry work.

- Option 3: Erich Hückel

- Developed the Hückel method, associated with aromaticity in organic chemistry.

- Focused on quantum mechanics and aromatic compounds, not coordination numbers.

- Option 4: Emil Fischer

- Notable for work on enzyme specificity (“lock and key” model) and carbohydrates.

- Awarded the Nobel Prize in Chemistry in 1902 for sugar and purine syntheses.
