Jensen Chem 110 Lesson 16 Page: 1 Lecture 38 Friday 11/22 Reading: Lesson 16–2 – 3 Know: Hess’s Law Heats of formation Calculating reaction enthalpy using heat of formation Reminder: Comprehensive Final Exam: Tuesday Dec 17 4:40 – 6:30 pm Thanksgiving Break: Nov. 25 – 29, no classes Start reviewing the previous material now and come up with a plan to review a bit every day - in addition to keeping up with the remaining new material - so the looming finals week is not overwhelming. Jensen Chem 110 Lesson 16 Page: 2 Exam 2 Concepts You Should Know: Lesson 06: Bonding What is covalent bonding and how is it different from ionic bonding? How can you tell if a substance is covalently bonded? What is the octet rule? What is the preferred valence of an atom? What are the two types of multiple bonds and how do their bond lengths and strengths differ? Lesson 07: Molecular structure How do we use electronegativity difference between two atoms to predict the relative polarity of a bond is ionic? What are the steps to draw Lewis structure? What is formal charge? How do we use it to determine the best Lewis structure of a molecule? What molecules will have resonance structures? Which resonance structure is the best picture of the bonding? How does resonance affect bond length and strength?

Jensen Chem 110 Lesson 16 Page: 3 Be able to identify molecules that violet the octet rule. Be able to identify molecules that have expanded valence shell. Lesson 08: Molecules in 3D What are the names and associated bond angles of the electron domain geometries and molecular geometries we have studied? What are the steps to determine the electron domain and molecular geometries of a molecule? How do you use the VSEPR rules to understand local geometry in larger molecules?
