Students have asked these similar questions
Consider peroxynitrite (chemical formula: ONOO−), a structural isomer of the nitrate anion. It is generated in the cell when nitric oxide (NO) reacts with the superoxide radical anion (O2-.). Peroxynitrite is a potent oxidant and nitrating agent and can lead to DNA and protein damage (this is the complete question)
Draw the correct Lewis structure for peroxynitrite and indicate approximate bond angles.
Tell how many molecular degrees of freedom of motion are present in peroxynitrite and what motions they correspond to.
Based on formal charge considerations, which of the following would likely be the correct arrangement of atoms in hypochlorous acid: HOCl or OClH?
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.
