Question : 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?
Option 1: Friedrich Kekule
Option 2: Rosalind Franklin
Option 3: Erich Huckel
Option 4: Antoine Lavoisier
Correct Answer: Erich Huckel
Solution : The correct option is Erich Huckel.
German scientist and physicist Erich Huckel put up a theory in 1931 to assist in identifying whether an aromatic property would be present in a planar ring molecule. According to his rule, an aromatic, cyclic, planar molecule possesses 4n+2 electrons. Hückel's Rule is the name given to this principle.
