Control of Structure

Control of Structure. Why do elements and compounds adopt one structure as opposed to another?. Thermodynamics Review: G = H - TS. Bond Strength Favored by strong bonds. Freedom of Movement Favored by more particles. Temperature Control?. Thermodynamics Review: G = H - TS.

  1. Control of Structure Why do elements and compounds adopt one structure as opposed to another?

  2. Thermodynamics Review: G = H - TS Bond Strength Favored by strong bonds. Freedom of Movement Favored by more particles. Temperature Control?

  3. Thermodynamics Review: G = H - TS Bond Strength Favored by strong bonds. Freedom of Movement Favored by more particles. Example: Cl-Cl vs. ClCl Cl-Cl bond strength = 242 kJ/mol So (Cl) = 165 J/Kmol So (Cl2) = 223 J/Kmol

  4. Bonding Concerns and Trends: Number of bonds Type of bonds: sigma vs. pi

  5. Number of Bonds Possible: F, O

  6. Number of Bonds Possible: N, C

  7. Lewis Base Activity Expands # Bonds

  8. sigma vs. pi bonding: Lewis structure examples

  9. Shapes of sigma and pi bonds

  10. sigma vs. pi bonding: shapes, strength and trends
