Document Summary
Guided reading/note outline 2 - molecules week 1&2. Learning objectives, readings, topics, and resources: apply the octet rule to the construction of lewis structures for multi-atom, multi-element molecules. Be able to recognize violations of the rule. (sections 9. 4 9. 6 and 9. 8) Examples 1, 3, 4 exceptions to the rules: know what resonance is and be able to draw resonance structures. (section 9. 7) Example 2 pg 6-5: show how formal charges can facilitate the generation of better lewis structures. (section 9. 9) 1: apply vsepr theory to lewis structures to determine approximate molecular geometries. (section 10. 1) Central atom with two, three, or four valence-shell electron pairs. Steps in the prediction of geometry by the vsepr model. Bond angles and the effect of lone pairs. Central atom with five or six valence-shell electron pairs. Bonding and molecular structure: shapes of molecules and ions.
