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...
3) for one resonance structure of a nitrate(NO3-)
provide the:
a) Lewis structure
b) formal charge on each atom
c)name of the electro pair(electron domain)
geometry
d) hybridization of the central atom
e)name of the molecular geometry (shape)
Draw a Lewis structure for PSF3 in
which the octet rule is satisfied on all atoms and show all
NONZERO formal charges on all atoms.
Do not include the overall ion charge in your answer.
Based on formal charge, what is the best Lewis structure for the
molecule?
Draw a Lewis structure for SO2 in which all atoms obey the octet rule. Show formal charges. Do not consider ringed structures.
Draw a Lewis structure for SO2 in which all atoms have a formal charge of zero. Explicitly showing the zero charges is optional. Do not consider ringed structures.
Draw a Lewis Structure for each of the following.
Identify any that would have resonance structures and draw all
possible structures.
Determine the formal charge on all the atoms in each of the
molecules.
Determine the molecular geometry (giving the appropriate name)
using VSEPR theory.
Determine if the molecule is polar or nonpolar.
Give the hybridization of the central atom.
