    Furan is an aromatic compound because of Huckel's rule. One of the lone pairs of electrons on the oxygen goes on to the ring and giving it a 4n+2 system.

    pi electrons = 2 × 2 = 4

    (4-2)/4 = 1/2
    It is not aromatic

    That's not Hückel's rule, or at least not in the form I understand.

    See prize fight answer.
