a.) oxygen difluoride
b.)phoshorus trichloride
c.)xenon difluoride
d.) tetrachloroiodate ion

For VESPR problems, you need to be able to do a little accounting of electrons.

Step one is add up all valence electrons, for a total.
Step two is to pick the central atom, and draw a skeleton.
Step three, is to subtract 2 electrons from the total for each bond drawn in the skeleton drawing.
Step four is to fill the valence shells of the X atoms (the atoms attached to the central atom)
Step five is to subtract the added electrons from the total
Step six is to add all leftover electrons to the central atom as a lone pair
Step seven is to assign an AXE formula and deduce shape.

1.)For each of the following covalent compounds deduce their molecular shape and the possible hybridization of the central atom:
a.) indium(I)iodide
Indium is in group 3
Iodine is in group 7
Total electrons is 10
Draw skeleton (pretty easy)
10-2 electrons for the one bond
fill valence shell of the iodine
8-6 electrons
2 electrons will go on the Indium as a lone ...
