Draw the lewis dot structure and all resonance structures for
the dithiorcarbonate molecule (S2CO -2).
Which lewis structure is the best for this structure?(formal
charge)
Draw the Lewis structure (including resonance structures) for
methyl azide (CH3N3). Draw the molecule by placing atoms on the
canvas and connecting them with bonds. Do not identify the charge
on each of these species. Include all lone pairs of electrons.
Resonance structures are Lewis structures drawn for a molecule
when more than one Lewis structure is needed to explain the
molecular structure. Resonance results in extended
__________?
of some electrons among more than two nuclei of the molecule.
This results in lowering of kinetic and potential energies that
imparts added stability to the molecule.
Note. In covalent bond formation the bonding electrons are
delocalized between only two atoms. Resonance is taking the
delocalization of electrons between nuclei to the next...
1) draw the most appropriate Lewis structure, 2) all resonance
structures, and 3) formal charges for all atoms having any. Then,
determine the electron and molecular geometries for each
structure.
