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?
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.
