Final answer:
Huckel's numbers are used to predict the aromaticity of conjugated hydrocarbon systems in organic chemistry. The equation for Huckel's numbers is n = 4s + 2p, where n is the number of Huckel's numbers, s is the number of sigma bonds, and p is the number of pi bonds. Aromatic molecules have enhanced stability.
Step-by-step explanation:
Huckel's numbers are used in the field of organic chemistry to predict the aromaticity of conjugated hydrocarbon systems. The equation for Huckel's numbers is given by:
n = 4s + 2p
where 'n' is the number of Huckel's numbers, 's' is the number of sigma (single) bonds, and 'p' is the number of pi (double) bonds. Huckel's numbers are used to determine whether a molecule is aromatic (n is divisible by 4) or anti-aromatic (n is divisible by 4 minus 2). Aromatic molecules have enhanced stability.
