Students have asked these similar questions
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.
Consider the following ions: NO2−NO2−, CO32−CO32−, and ClO4−ClO4−. For each of these, you should use a Lewis structure that satisfies the octet rule. Which of these ions will exhibit resonance among multiple equivalent Lewis structures that satisfy the octet rule?
Hydrogen azide (HN3) is a shock-sensitive liquid, which means it explodes when subjected to a physical shock. The HN3molecule contains two N-N bonds with bond lengths 113 pm and 124 pm. The H-N-N bond angle is 112°. Draw two Lewis structures of HN3 that obey the octet rule. What is the formal charge of each atom in your structures? Which structure is most consistent with the experimental data?
