Draw Lewis dot structures, including appropriate resonance forms, and assign formal charges
to each of those structures, for the molecule urea, with chemical formula NH2CONH2. You
should find at least 3 such structures, some of which will have formal charges which are
nonzero. Using VSEPR theory, predict the NCO bond angle.
These boards do not support Lewis dot structures. Here is a site that shows the structure; perhaps it will be of some help in setting up the dot structures.
