Using the Cahn-Ingold-Prelog sequence rules,assign priorities to the groups around the chiral carbon in carvone. Draw the structural formulas for (+)- & (-)-carvone with the molecules oriented in the correct position to show the R & S configurations.

    We can't draw structures on this board.

    They are drawn on the wikipedia page

    http://en.wikipedia.org/wiki/Carvone

    I would be tempted to redraw them using a Fisher projection http://en.wikipedia.org/wiki/Fischer_projection
    to demonstrate you understand the application of the C-I-P rules.

    Well, if I were you, I would cancel it, and reatke it if you feel like you understood the material well enough to still semi remember it next year. However, the next time you take it, I would read through the textbook and then read through a review book. I would also suggest doing a lot of practice questions from old released tests (you can find those on the College Board website). Also, what grade are you in? If you are a rising senior it may not even be worth retaking depending on the college you are going to and the major you are choosing. Otherwise, it wouldn't really hurt to try again (you'd just be out about $100).
