    None of these are aromatic except b. Choice D has 4 electrons, is not aromatic, but what is antiaromatic, and do we need to know that for the DAT? Ive never even heard of it....

    Got a 25 though :p

    That was my first reaction, but do you think an antiaromatic question could possibly be on it???

    Also, wiki makes no difference between non-aromatic and anti-aromatic.

    Yeah im sure they would test on it. If it is in your ochem text and the kaplan book (which im not sure about) it can be in there. I remember it in my ochem class. Aromatic compounds are the same but instead of 4N they are 4N+2, thats the only difference I know about.

    that IS the only difference between aromatic and antiaromatic. if a compound is neither aromatic nor antiaromatic, then it's nonaromatic.

    Wait, so ANTIaromatic compounds are 4n? Non aromatic compounds are neither 4n+2 or 4n, and aromatics are 4n+2?

    Antiaromatic wasnt in my textbook, and I dont remember it from the classes either ;)

    Aromatic is a cyclic, conjugated, and 4N+2
    Antiaromatic is cyclic, conjugated and 4N
    Non aromatic is anything else

    A compound is anti aromatic if it fulfills the following conditions: It has to be cyclic, planar and have an even pair of pie electrons.
    A compound is aromatic if it is cyclic, planar and has an odd pair of pie electrons
    A compound that is neither aromatic or anti aromatic is non aromatic.
    and yes anti aromaticity is an important concept
