Unformatted text preview: Chem 102 lec 1c W’11 UPDATED on office hours: TR 330-430pm Enrol to OWL soon as possible! Last time: orientation a) discussed syllabus b) electron configurations c) Lewis structures: F 2 , NO 2- Today, We review: Chapt 8 material 1) rules for Lewis structures. 2) hydrocarbon line structures 3) multiple covalent bonds 4) resonance 5) bond polarity In addition: Chapt 9 material 6) VSEPR model and e domains 7) molecular polarity 8) hybridization Many atoms are most stable when full octet is formed. Lecture: 1c: (1) How to draw Lewis structure: 1) count # valence electrons 2) draw skeleton: central atom, peripheral atoms 3) draw single bond ; fill octet 4) recount the e’s 5) usually # bonds: C =4, O=2., H=1 (2) Do: NH 3 , NO 2 + (3) Do C 4 H 10 , C 6 H 6 (4) Drawing hydrocarbon skeletons using line structures. (5) Electronegativity and bond polarity (6) What is shape of the molecule?...
