Question

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.

Answer 1

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.
