Nov 21- Intermolecular Forces and Properties

Outcome: CH30‐MS2 Investigate how the properties of materials are dependent on their underlying intermolecular and intramolecular forces.[SI] Indicators: B. Differentiate between the different types of intermolecular (i.e., van der Waals [i.e., London dispersion, dipole‐dipole, hydrogen bonding and ion dipole], ionic crystal and network‐covalent) and intramolecular (i.e., nonpolar covalent, polar‐covalent, ionic and metallic) forces. C. Recognize […]
