Lewis dot structures of complex molecules

  1. Dec 6, 2009 #1
    1. The problem statement, all variables and given/known data
    determine the electron dot structure of molecules a and b
    http://session.masteringchemistry.com/problemAsset/1144353/2/MMAt.05.067.jpg


    2. Relevant equations

    3. The attempt at a solution
    A)

    ::O: H
    | |
    H-C=N-H


    B)
    H
    | ..
    H-C-N=C=O::
    |
    H

    I am not at all sure this is correct and the software that accepts answers for my school agrees with that assesment, any assistance will be greatly appreciated

    Your first answer has a single bond between the carbon and the oxygen. That oxygen also has six other electrons around it. Would that result in the oxygen having a charge? You also show the enamine (with friends like that, who needs enamines?) nitrogen having four bonds to it. What would the charge be for that? Does your assignment want you to postulate neutral species? I'm betting it does.
