Formamide, HC(O)NH2, is prepared at high pressures from carbon monoxide and ammonia, and serves as an industrial solvent (the parentheses around the O indicate that it is bonded only to the carbon atom and that the carbon atom is also bonded to the H and the N atoms). Two resonance forms (one with formal charges) can be written for formamide. Write both resonance structures, and predict the bond angles about the carbon and nitrogen atoms for each resonance form. Are they the same? Describe how the experimental determination of the HNH bond angle could be used to indicate which resonance form is more important.
The NO3 ion displays three resonance structures, one of which is shown below. 1. :O: (a) Find the formal charge on each of the atoms in the nitrate ion.

In the following Lewis structure of [SiF6]², every atom, bond and lone pair is positioned. To complete the structure, drag the formal charge tags to the appropriate atom(s). Each marker may be used more than once, or not at all. If an atom has a formal charge of zero, do not drag a tag to it. When you drag the marker in, place the little crosshairs in the upper left corner of the marker directly over the atom(s) in question (not above them). :F: :F : :ד: Si 1 :F: 0 0 0 2+ :H: Ë: 0 2-

Calculating Formal Charge: Formal charge is calculated for each atom in a structure. It provides information about the stability and reactivity of the atom in the molecule. Formal Charge = Valence Electrons - 1/2 Bonding Electrons - Non-bonding Electrons For example, the formal charge on the carbon of methane is calculated here. Carbon has 4 valence electrons. There are 8 bonding electrons around it.
