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
