    With a couple waitlists...and no word from a few other schools, I've started studying to retake the DAT. I forgot how much I dislike Orgo!!! :rolleyes: But this time around I'm going to eat, sleep, and breath it for the next 3 months...

    I hate studying anything the second time around. I took DAT in July 2005, and if I dont get in somewhere soon, I'll have to retake it just because the scores are only valid for 3 years :scared:

    Its always easier the more you do something, so you should have a easier time re-learning it. granted it sucks but atleast your not learning it for the first time.
    Toluene + HNO3 + H2SO4 --> TNT!!!

    ugh.. as if you read my mind. I am retaking my DAT due to not having so much luck this past admission cycle... but what really sucks is having to literally re-learn orgo..... hey at least they don't have physics on DAT hahahhaha.... suckzors.

    I find Cliff's Orgo Quick Review to make it less painful.

    Orgo is sooo much fun!!!!

    But seriously, That stuff is just torture to learn. It's basically straight up memorization of really, really complicated formulas.. and then applying it to reaction paths. Torture!

    But it's kinda fun once you memorized everything and get down to the business of synthesis and analysis of the resulting products.

    Glad I'm done with orgo.. Good luck guys!

    i took my last ochem class after i took the dat, and after i got into dental school. tell me what kind of motivation is that?

    You guys are scaring people (such as myself) from Orgo I and II...

    I will be taking Orgo I (this coming september) along with Gen Chem II (plus lab) and Biology I (plus lab)

    I mean I hear it was a "tough" course... but you guys are making it seem like its impossible to do well :(

    No, just lots and lots and lots of time studying.

    What books are you guys using or have found to be helpful in studying orgo, ESPECIALLY if you didn't do so hot, and pretty much have to re-learn the stuff...

    You know whats worst then taking Orgo????....... Teaching the lab section and babysitting a bunch of lab students. Probably the worst thing is grading the lab reports, god do they BS ahahaha. Orgo is no problem for me its math that got me on the DAT.

    This is what they should really teach you in Orgo.

    How to make MDMA / MDA

    MDA (3,4-methylenedioxyamphetamine)

    The following synthesis is not meant to be carried out by a novice
    chemist, although it is not terribly difficult. For descriptions of
    how to carry out the procedures, a standard lab procedures reference
    manual should be aquired by the reader (or preferably the reader
    should take college organic chemistry).
    This is the synthesis for MDA which can be found on page 79 of
    Psychedelic Chemistry, which was first published in Chemical Abstracts
    52, 11965c (1958). The former however has the above noted
    typographical error of 75 ml 15% HCl being written as 57ml 15% HCl.
    The original article also has a typographical error. In the synthesis
    of MDA from the ketone it reads H2O2 where it should read H2O --
    following the former procedure would be explosive. As a side note,
    this is the same process of making the ketone from isosafrole as
    Shulgin uses in PiHKAL, thus the synthesis of the ketone is somewhat
    more verbose than the synthesis of MDA from the ketone.

    To a well stirred, cooled mixture of 34g of 30% H202 (hydrogen
    peroxide) in 150g 80% HCO2H (formic acid) there was added, dropwise, a
    solution of 32.4g isosafrole in 120ml acetone at a rate that kept the
    reaction mixture from exceeding 40 deg C. This required a bit over
    1 hour, and external cooling was used as necessary. Stirring was
    continued for 16 hours, and care was taken that the slow exothermic
    reaction did not cause excess heating. An external bath with running
    water worked well. During this time the solution progressed from an
    orange color to a deep red. All volatile components were removed under
    vacuum which yielded some 60g of a very deep residue. This was
    dissolved in 60ml of MeOH (methyl alcohol -- methanol), treated with
    360ml of 15% H2SO4 (sulfuric acid), and heated for 3 hours on the
    steam bath. After cooling the mixture was extracted with 3x75ml
    Et2O (diethyl ether) or C6H6 (benzene). Its recommended that, the
    pooled extracts can washed -- first with H2O and then with dilute NaOH
    (sodium hydroxide). Then the solvent is removed under vacuum to
    afford 20.6g 3,4-methylenedioxyphenylacetone (3,4-methylenedioxybenzyl
    methyl ketone). The final residue may be distilled at 2.0mm/108-112 deg
    C, or at about 160 deg C at the water pump.
    Add 23g 3,4-methylenedioxyphenylacetone to 65g HCONH2 (formamide)
    and heat at 190 deg for five hours. Cool, add 100ml H20, extract with
    C6H6 (benzene) and evaporate in vacuum the extract. Add 8ml MeOH
    (methyl alcohol -- methanol) and 75ml 15% HCl to residue, heat on
    water bath two hours and extract in vacuum (or basify with KOH and
    extract the oil with benzene and dry, evaporate in vacuum) to get
    11.7 g 3,4-methylenedioxyamphetamine (MDA).

    ===> To produce MDMA substitute N-methylformamide for formamide in the
    above synthesis.


    MDMA is (3,4-Methylenedioxymethamphetamine). The structure of the
    molecule (insofar as it can be rendered using ASCII) is this:

    From: Chemical & Engineering News. September 9, 1985.

    Kaplan blue book first, then destroyer or achiever questions to practice (maybe*)...I'm still on Kaplan so I'll let you know if it's enough prep. I'm trying to use textbooks as little as possible as the prep books are more focused on the specific topics appearing on the actual test.

    Can't we just say that chemical reactions are due to some sort of black magic and leave it at that? :eek:

    Thats what Biochem is for with all of the enzymes.

    AB+C + Enzyme ---> AC+B + Enzyme

    Enzymes = black magic
