Lewis Structures, Hybrid orbital

1. Draw the Lewis structure for OF2 (small 2 at bottom) What are its electron-pair and molecular geometries? decribe the bonding in the molecule in terms of hybrid orbitals.

2. Draw the Lewis structure for C1F 2 + (small s at bottom and small + at top) What are its electron-pair and molecular geometries? decribe the bonding in the molecule in terms of hybrid orbitals.

3.Tell what hybrid orbital set is used by the underlined atom in each of the following molecules or ions.
A) B1C3 (small 3 at bottom and the B is underlined)
B) NO2 + (small 2 at bottom and small + at top and Ni s underlined)
C) HCC13 (small 3 at bottom and the first C is underlined)
D) H2CO (small 2 at bottom and the C is underlined)

4. Give the hybrid orbital set used by sulfur in each of the following molecules or ions:
A) SO2 (small 2 at bottom)
B) SO3 (small 3 at bottom)
C) SO3 2- (small 2 at bottom small 2- at top)
D) SO4 2-   (small 4 at bottom small 2- at top)
