We are unable to draw diagrams on these boards. However, here is a site that gives the structure for #1 together with the resonance structures. If I find the structure on the web for #2 I shall post it. http://www.chem.ucsb.edu/~genchem/Chem1CS03/examanswers/final_white.pdf

3H bonded to C-N(N has lone pair of e-)= C = O(O has 2 lone pairs of e-)
