Homework Help: Chem question on dash-wedge structures

  1. Sep 18, 2008 #1
    1. The problem statement, all variables and given/known data

    how would you draw this structure in 3d using dash-wedge representation?


    From my guess, I drew the N=C=C as being parallel, and the two hydrogens coming off the second C without having any dashes or wedges, but curving at 120 degrees from the carbon. For the HN, I had the H represented using a dark wedged line. To represent the N I had a dashed line going out, with 2 electrons depicted at the end of that dashed line to represents Nitrogens 2 free electrons.

    Is this accurate and if not what is the right way? And what is the hybridization of the N in HN=C=CH2?

    Look up allene on wikipedia.
