Due to the absence of lone pairs, NO2Cl has a symmetrical charge distribution. This answer is: Study guides. Now in the NO2Cl molecule, you have to put the electron pairs between the nitrogen atom (N), oxygen atom (O) and chlorine atoms (Cl). This concludes our article on the geometry, hybridization, polarity, and Lewis structure of NO2Cl. (a) Write a Lewis diagram for each of these molecules, indicating the formal charge on each atom. In order to anticipate the geometry of the molecules, the Valence Shell Electron Pair Repulsion Theory (VSEPR) is used. The results of these studies and calculations using density functional theory are consistent with the oxidation being metal-based, resulting in an uncommon Pd(2)(5+) species with a Pd-Pd bond order of 1/2.
