1 Highlights of CH301: Key concepts and skills Stoichiometry (balancing equations and mole problems) Electromagnetic radiation Orbitals and energy levels Electron configurations Quantum numbers Periodic properties Ionic versus covalent bonding Lewis dot structures Resonance Single, double and triple Bonds Octet rule Polarity and dipole moments Bond strengths and bond lengths VSEPR and Valence Bond models Sigma and pi bonds Hybridization Molecular orbital theory Gas laws (combined gas law, ideal gas law) Stoichiometries of reactions Limiting reactant and percent yield Intermolecular forces: dipole-dipole, London/dispersion, hydrogen bonding, dipole-induced dipole Work, heat, enthalpy Calculation of reaction enthalpies Heats of formation Entropy Gibbs Free Energy: Spontaneity of reactions (enthalpy and entropy)

2 By the end of the semester, you should have mastered these concepts : 1) Stoichiometric calculations (moles, yield, limiting reactant, balancing equations) 1) An understanding of the structure of atoms (nucleus, arrangement of electrons in orbitals). 1) Elements have predictable properties based on their placement in the periodic table (electron configurations). 4) An understanding of covalent versus ionic bonding and the properties associated with covalent versus ionic compounds. 5) How molecules are constructed (bonding patterns, shapes of molecules, overlap of orbitals, resonance, single/double/triple bonds) 6) Properties and behaviors of gases, liquids and solids (intermolecular forces) 7) Thermodynamics of reactions: why some reactions occur and others don’t occur; whether reactions give off or absorb heat; the importance of disorder
