The MINDO/2 and CNDO/2 methods have been used in calculations on the HC (NO2)2 − anion geometry. Minimum total energy corresponds to planar configuration with nitro group equivalence.
(a) The bonds in nitrite ion, NO. 2 –, are shorter than the bonds in nitrate ion, NO. 3 –. According to the Lewis electron-dot diagram, two resonance structures are required to represent the bonding in the NO. 2 – ion. The effective number of bonds between N and O is 1.5. Three resonance structures are required to represent the bonding in the NO. 3 – ion.

Dec 13, 2018 · Step 3: Use the VSEPR table to determine the H 2 O electron geometry: four substituents is tetrahedral. While the electron geometry is tetrahedral, the H 2 O molecular geometry is bent. (See below for an explanation of the difference between the two geometries) The bond angle for this molecule is 109 0. H 2 O molecular geometry is bent.
how many valence electrons NO2- lewis structure. Nitrogen and oxygen has five and six electrons respectively. Because two oxygen atoms exist, there are 12 valence electrons. Due to -1 charge, one more electron comes to contribute to valence electrons. So number of total valence electrons is 5 + 12 + 1 = 18.
