What possible error(s) exist in the Lewis structure (assume we are trying to represent the best
possible Lewis structure for the NO₂S ion knowing N is the central atom in this polyatomic ion)?
[:ö==S:
N=
CO
:O:
The best structure would have double bond and two lone pairs on each oxygen atom and a single bond with
three lone pairs on the sulfur.
There are no errors. This is the best possible structure.
The Lewis structure above does not minimize formal charges, thus is the not the best possible structure.
The nitrogen atom has an expanded octet, and this structure is impossible.
The Lewis structure contains the wrong number of electrons, thus this structure is impossible.
For the following three Lewis structures, list whether they are correct or incorrect:
alt-text for image above: The first image shows a proposed Lewis structure for Freon-13, CClF3, that has a central carbon singly bonded to a three chlorine atoms and a fluorine atom. Each chlorine and the fluorine have 3 lone pairs of electrons around them. The second image shows a proposed lewis structure for the nitrite ion, NO2-, as a central nitrogen atom between two oxygen atoms. The O atom on the left has three lone pairs of electrons and then a single bond between the N. The right O atom has two lone pairs of electrons and a double bond with the N atom. The N atom has a single lone pair of electrons in addition to the double and single bonds with oxygen atoms. The third image shows diazomethane, CH2N2, and the proposed Lewis structure has a carbon singly bonded to two H atoms, then doubly bonded to a nitrogen. The nitrogen is doubly bonded to the second nitrogen, and the second nitrogen has…
