Which molecule or ion is not planar? Describe the bonding in the nitrite ion in terms of a combination of hybrid atomic orbitals and molecular orbitals. 2 Answers. As that set of atoms are more stable in that configuration while an additional electron is available, the “octet rule” clarifies that an atom is more stable if it has a filled outermost orbital of s and p. There are one s, and 3 p’s, and each orbital carries 2 electrons, so, as a result, eight is the good number. Arrangement et géométrie de l'ion nitrite. The Lewis structure of NO2 has 17 valence electrons. is by counting the bonds and lone electron pairs around the nitrogen atom and by drawing the Lewis structure. The molecular geometry or shape of a molecule depends on the number of bonding pairs and lone pairs of electrons around the central atom. Since the Nitrogen Dioxide (NO 2) has an extra electron in a nitrogen atom’s orbital, it will result in a higher degree of repulsions. bent. ChEBI. James. D)tetrahedral. Finally, you will use the 3D-Angles program individually to master the determination of coordination number (i.e. While coming to NO 2 (-), that is, nitrite ion, the N-atom has sp 2 hybridization; thus, it adopts the bent geometry, for NO 2 (-), and the actual O-N-O bond angle is 115 ° (slightly deviated from the expected 120° due to the repulsion between lone pair of electrons and interacting bond pairs).
