When you are doing resonance structures, is it better to have a neutral charge on the entire molecule and have one atom without an octet, or is it better for all the atoms to have an octet and there be a formal charge on an atom(s)? The molecule I am questioning is H2CN2. The molecule will be neutral if the second N has 2 valence pairs, and is bonded singly to the other N, but it would not have an octet. If there is a double bond between the two N's, one of the Ns will be (+), and other will be (-) but both Ns will have octets. Got my first orgo test tomorrow Thanks for any help!
