Chem 152A Review Topics Chapter 13 A L Kwiram Why do molecules form What are the two contributions to the potential energy in the hydrogen moleculeion Why do we use the term quotmolecular orbitalquot MO Know pictorial representation for molecular orbital molecular bond H2 Meaning of terms quotbondingquot and antibonding orbitals and how they differ generally in terms of electronic distribution probability Potentia energy curve vs R for H2 and H2 mportance of net OVERLAP Understand 39 a quot quot concept 3 Understand origin of dipole moment polar bond Bond energies and how to calculate AH of reaction from bond energies Bond length strength trends for diatomic molecules Geometry of polyatomics via Repulsion Theory onic bonds how polar a bond is Lattice stabilization energy and net AH to go from elements in standard state to ionic crystal Know how to carry out such a calculation Know how to construct Lewis dot structures octet rule recipe for using Special stability of noble gas configurations stability of half filled shells Exceptions to octet rule how to handle deficit of electrons excess electrons Role of central atom What are typical oxidation states of elements and how is this related to number of bonds an atom typically forms How and when to form double and triple bonds Concept of resonance in forming Lewis dot structures Forma charge and how do decide between alternate structures that seem to satisfy the octet rule Valence Shell Electron Pair Repulsion Theory VSEPR Theory recipe for using Distinguish between electronpair structure where the electrons are and molecular structure where the atoms are Critical role of central atom how is it chosen Relative energetics of nn gt nb gt bb interactions and how that affects bond angles Understand important role that lone pairs nonbonded pairs play in structure Understand the different kinds of molecular structures and the names for them Linear triangular trigonal planar trigonal 39 39 39 39 etc 39 39 39 39 square planar square pyramidal bent etc How bond angle changes with increasing number of lone pairs How bond angle changes as you go from negative ion to neutral to positive ion Species with an odd number of electrons are magnetic they have a magnetic dipole moment that orients in a magnetic field just like a molecule with an electric dipole moment orients in an electric field The magnetic property is due in this case to the magnetic moment of the unpaired electron I l quot quot trends yT Chem 152A W O6 Review Topics Chapters 9amp10 A Kwiram Review Topics for Chapter 9 Meaning of system and surrounding Signi cance of the two modes of exchanging energy heat and work Depending on the process the overall distribution between q and w change but their sum qw E is constant Meaning of a state function and why q and w are not state functions or thermodynamic functions What are the 39measurables39 soated adiabatic isothermal reversible spontaneous w Popp AV if only PV work considered
