page 1 of 4 1/14/11 Chem 102- 02 PE 120 lecture 2c-Winter, 2011 Lec2c Announcement: Week 4 schedule and Test #1 Last time: 1) hybridization: 5 types & shapes 2) multiple bonds 3) molecular polarity 4) intermolecular interactions 5) pop quiz 1 Today: announce Test 1 0) Go over the pop quiz 1) Review intermolecular interactions 2) interpret figure 9.20 3) polar vs non polar 4) Gases (chapter 10) LECTURE 2c (0) the pop quiz. Remember to go from Lewis structure to hybrid orbitals: Lewis e domain hybrid structure geometry orbital (1) Intermolecular interactions these are weak, they can arise from induced dipole, dipole, or H-bonded to enegativ atom. Go over examples: (polar and nonpolar molecs) H 2 O CH 4 CH 3 OH (2) Usually, we can say: polar =hydrophillic (esp. if can H-bond) nonpolar= hydrophobic hydrophobic vs hydrophilic Common nonpolar molecules hydrocarbons => hydrophobic (e.g. fats, lipids, oils)
