Chapter Objectives for Chapter 11, Petrucci, 9th ed. - Edited for Chem 1AA3. 11 Chemical Bonding II: Additional Aspects The most important objectives appear in bold font. Please note for Chapter 11 we are only considering sections 11.1-11.4, in addition to the class notes. 1. Explain the fundamental basis of valence bond theory, the meaning of the term hybridization , and explain why hybrid orbitals are often used to describe bonding in molecules rather than pure atomic orbitals. 2. Write hybridization schemes for the formation of sp , sp 2 , and sp 3 hybrid orbitals from atomic orbitals; predict the geometric shapes of molecules, or at certain atoms within molecules, in terms of the pure and hybrid orbitals used in bonding. 3. Use the relationship between VSEPR theory and valence bond theory to predict molecular geometries and bonding schemes (pictures of orbitals in a molecule). 4. Describe multiple bonds between second period elements (or higher period

Describe a double bond as one sigma and one pi bond and a triple bond as one sigma and two pi bonds. Explain why a pi bond is weaker than a sigma bond. Label a carbon-carbon double bond as stronger than, but less than twice as strong as, a carbon-carbon single bond. Label a carbon-carbon triple bond as stronger than a carbon-carbon double bond, but less than three times as strong as a carbon-carbon single bond. 6. Label the hybridization of atoms and propose plausible bonding schemes from Lewis structures or from experimental information about molecules (that is, bond lengths, bond angles, geometries, and so on)....
