Answer 1

The correct answer is Erich Huckel.Key Points

The German chemist and physicist who 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 is Erich Huckel.
Huckel's rule helps in determining whether a compound is aromatic or not by checking the number of pairs of electrons in its pi system.

Additional Information

Friedrich Kekule was a German chemist who proposed the structure of benzene in 1865, which is a six-membered aromatic ring with alternating double bonds.
Rosalind Franklin was a British biophysicist who played a crucial role in discovering the structure of DNA.
Antoine Lavoisier was a French chemist who is considered the father of modern chemistry for his work in understanding the nature of combustion and oxygen's role in it.
Hence, the statement is correct, and Erich Huckel is the German chemist and physicist who proposed Huckel's rule in 1931.
