Which German chemist and physicist proposed that an aromatic compound must have an odd number of pairs of electrons,Which can mathematically be written as 4n+2 (n = 0,1,2,3, etc.) in 1931?
Friedrich Kekule
Rosalind Franklin
Erich Huckel
Antoine Lavoisier
- Correct Answer: Option 3, Erich Hückel.
- Hückel proposed the 4n + 2 rule for aromaticity in 1931. This rule helps determine the stability of aromatic compounds.
- Option 1, Friedrich Kekulé
- Kekulé is renowned for suggesting the ring structure of benzene, which is foundational in understanding aromatic compounds.
- Option 2, Rosalind Franklin
- Franklin was pivotal in photo 51, which contributed to proving the helical structure of DNA. She wasn't involved in aromaticity.
- Option 4, Antoine Lavoisier
- Lavoisier is often called the "Father of Modern Chemistry," known for his role in the law of conservation of mass, not aromatic chemistry.
