Problem: Nitromethane is an organic compound with the molecular formula CH 3NO2. Image Transcriptionclose. In the resonance structure of nitrous acid lone pair of oxygen converted to the covalent bond and vice versa.Also, the formal charge on first oxygen is +1 and on second oxygen is -1. The C is SP3 hybridized, an the N SP2. It asks to draw the CH3NO2 lewis structure and I drew it as C with 3 H around it in single bonds and an N attached to the C in a single bond and the two O in double bonds attached to the N with two pairs of lone electrons each. 0 0. ClO- N2 25. It's using the same number of valence electrons. In a Lewis structure, formal charges can be assigned to each atom by treating each bond as if one-half of the electrons are assigned to each atom. The Lewis structure of CH3O- ( the methoxide ion) should be as follows: A C atom is placed in the middle, single bonded to three H atoms. The oxidation number of N is +1, whereas the formal charge … Draw the best Lewis structures for NO+, NO2-, NO2H, and NO3-.

The formal charge of N is +1, i.e. This is Dr. B., and thanks for watching. We'll start with nitromethane, \(\ce{CH3NO2}\). Because it has 2 inner shell electrons, it has a half share of the 6 electrons that comprise the 3xxN-H bonds, and it gets the full contribution from the lone pair of electrons: 2+3+2=7e^-. Knowing the formal charge on a particular atom in a structure is an important part of keeping track of the electrons and is important for establishing and predicting the reactivity. You could also draw the structure, methyl nitrite, as shown here. Nitromethane is a primary nitroalkane that is methane in which one of the hydrogens is replace by a nitro group.
