Homework Help: Stereochemistry, HELP

  1. Nov 6, 2007 #1
    Stereochemistry, PLZ HELP!!!

    ok far left is the original problem

    i manipulated it so that hydrogen and cyanide is facing me, but in order to determine R/S configuration. hydrogen must be going away from me, correct? so i flipped it so that it is not going away from me, and i determined it to be S.

    but on paper, for correct representation of a Fischer Projection, i would draw the one that has my horizontal plane coming towards me, correct? (the one circled)

    plz confirm this for me!!! any advice is appreciated.
