Day 14 skills review

  • Due No Due Date
  • Points None

DAY 14, Terms to know:

Sections 7.2-7.3, 5.7: molecular geometry, bond angle, molecular polarity, intermolecular forces (van der Waals forces), dipole-dipole interactions, hydrogen bonding, London forces, polarizability, instantaneous dipole, induced dipole, ion-dipole, polyatomic ions, hydrate, anhydrous

DAY 14, Specific outcomes and skills that may be tested on exam 2:

Sections 7.2-7.3, 5.7

  • Be able to determine direction and relative magnitude of overall molecular polarity by analyzing molecular geometry, individual bond polarities, and formal charges
  • Be able to list the types of intermolecular forces that exist and give examples of molecules that would have those forces of attractions and WHY
  • Given a molecular formula or a Lewis structure, be able to determine what types of intermolecular forces would likely to be present between two molecules
  • Be able to explain how hydrogen bonds are different from covalent bonds and how they are different from other types of dipole-dipole attractions
  • For a given set of molecules, rank them in order of increasing strengths of intermolecular attractions
  • Given a formula including a polyatomic ion, be able to predict which atoms present are bonded through ionic bonds and which atoms are bonded through covalent bonds
  • Be able to predict the chemical formula for an ionic compound involving polyatomic ions
  • Be able to recognize hydrates, write and read their formulas, and describe the attractions present in hydrates
