    Can someone explain to me what the n stands for in Huckel's rule. The equation to determine if a compound aromatic. The equation is (4n + 2)pi electron. I know n is a positive interger, but looking at the compound what are we counting?


    Thanks ;)

    Hunkels rule is 4n+2 = X

    where X is the number of pi electrons + lone pair electrons (only IF the pair is arranged so that it is oriented perpendicular to the plane of the ring)

    where n is a positive integer.


    If n ends up to be an integer, then it is aromatic.
