Structureand Molecular Properties

Summer 2012

- Syllabus
- ChemDraw
- Structures and intermolecular forces

- Virtual ChemBook, Elmhurst College

- Hydrogen bonding
- Acceptor/donor

- Dipole/dipole
- Dipole/induced dipole
- Induced dipole/induced dipole
- Also called London dispersion forces

VDWs Forces

- If molecules are about the same mass
- H-bonding > Dipole-dipole > Induced dipole

- Induced dipole is weakest interaction, but as surface area increases, cumulative effect can overcome stronger IMF
- Strategy for predicting relative boiling points

- “Like dissolves like”
- Based on IMF

- Miscibility spectrum
- Density
- Organics (0.7 g/mL)
- Aqueous (1.0 g/mL)
- Halogenated (1.3 g.mL)
