VSEPR and Hybridization Problem Set
1. Draw the following molecules according to Valence Bond theory, label all orbitals and sigma and pi bonds in each.
a) H2CCl2b) C2H3Clc) H3C – CH = CH – C = C - H
2. Use VSEPR theory to predict bond angles in these molecules.
a) methaneb) ammoniac) water
3. Use VSEPR theory to predict the shapes of the following species.
a) CO2 c) SCl2
b) SiCl4
4. The molecule CO2 has two carbon – oxygen double bonds. Draw the bonding in the CO2 molecule using hybridized orbitals for carbon and oxygen.
5. What type of hybrid orbitals are involved in the bonding of each atom in the following molecules?
a) H2Ob) H2C = Oc) N ≡ C – C ≡N
6. Describe the differences between the members of each pair of terms.
a) sigma bonds and pi bondsb) sp2 and sp3 hybrid orbitals
7. Give the angles between the orbitals of each of the following hybrids.
a) sp3 hybridsb) sp2 hybridsc) sp hybrids
8. What are the hybrid orbitals of each carbon atoms in the following molecules?
a) H3C – CH3
b) H3C – CH = CH2
c) CH3 – C ≡C – CH2OHd) CH3CH = Oe) CH3COOH
9. The molecule H2C = C = CH2 is linear (all 3 C atoms lie in a straight line). What are the hybridization states of the C atoms? Draw diagrams to show the formation of sigma bonds and pi bonds in this molecule.
