Write a Lewis structure for the phosphorus trifluoride molecule, PF3. Is the octet rule satisfied for all the atoms in your structure? (b) Determine the oxidation numbers of the P and F atoms. (c) Determine the formal charges of the P and F atoms. (d) Is the oxidation number for the P atom the same as its formal charge? Explain why or why not.
Solutions
Expert Solution
The octet rule is indeed satisfied for each atom in PF3.
The oxidation number for each F is -1. The Oxidative number for
P is +3. So they balance out.
Formal charge of P -> 0
Formal charge of F's -> 0
The formal charges on both the P and all the F's is 0.
The formal charge for p is not the same as its oxidative number
because the two quantities measure different things.
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?
For a molecule of Phosphorus trichloride, PCI3:
A) Draw the Lewis structure of this molecule. Using the Pauling
electronegativity scale, determine which bonds are polar; show them
on the structure using the S+/S- notation.
B) Is this molecule polar? Explain briefly why or why not.
C) What type of intermolecular forces should exist between two
PCI3 molecules?
A valid Lewis structure of ________ cannot be drawn without
violating the octet rule.
a)
NI3
b)
SO2
c) ICl5
d) SiF4
Please show the Lewis structure for each so I can try to better
understand.

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.
The correct Lewis structure for the boron trichloride molecule has an incomplete octet around boron. Draw this Lewis structure and three resonance structures of the molecule in which the octet rule is satisfied for both the B and Cl atoms. Show formal charges on all structures. Explain why the Lewis structure for boron trichloride is best written with an incomplete octet around boron.
