Click in the appropriate box for each question, then click "Done" at the bottom. 10 marks for each correct answer. Hints cost 5 marks each.
1. What kind of hybridization of oxygen's atomic orbitals is there in the water molecule? sp sp2 sp3 sp3d sp3d2
2. An octahedral species such as SF6 always has what kind of hybridization of the central atom? sp sp2 sp3 sp3d sp3d2
3. If a central carbon atom is sp2 hybridized, what shape of molecule results? linear trigonal planar tetrahedral trigonal bipyramidal octahedral
4. If a carbon atom is sp hybridized, how many p-orbitals are left over to make p bonds?
0 1 2 3
5. If two carbon atoms are bound via overlap of sp hybrids, how many C-C s-bonds and how many C-C p-bonds result? 0s, 4p 1s, 2p 2s, 2p 3s, 1p 2s, 1p
6. What kind of hybrid orbitals would the carbon atom have in formaldehyde, H2C=O? sp sp2 sp3 sp3d sp3d2
7. What kind of hybrid orbitals does the Xe atom use in a molecule of XeOF4? sp sp2 sp3 sp3d sp3d2
8. Shown below is a molecule of ethylene, C2H4. What kind of hybridization would you expect for the C atoms? sp sp2 sp3 sp3d sp3d2
9. Where are the electrons in a p bond and those in a s bond? The p electrons stay between the atoms, and the s electrons are delocalized. The s electrons stay between the atoms, and the p electrons are delocalized. Both the s and p electrons are delocalized. Both the s and p electrons stay between the atoms. None of the above
10. Why do the planes of C atoms in graphite slide so easily over one another? There are no bonds holding the planes together. There are very few bonds between the planes. There are sp2 hybrids holding the planes together. There are s bonds holding the planes together. There are p bonds holding the planes together.
