CHEMISTRY OF ORGANIC AND BIOLOGICAL MOLECULES 1

Fall 2001

For the second examination, you should be able to:

  1. Explain the concept of the mole and using unit factor conversion, to convert between moles, mass, and number of particles.
  2. Understand the meaning of chemical equations.
  3. Calculate the amount of reactant consumed and product produced given a chemical equation, and the masses of starting material.
  4. Write the molecular, ionic, and net ionic equations for the reactions of salts in water.
  5. Identify precipitation reactions, and predict the products of precipitation reactions.
  6. Define an acid and a base, identify acid/base reactions, and predict the products of that reaction.
  7. Define oxidation, reduction, oxidizing agent, reducing agent, and oxidation numbers.
  8. Identify redox reactions and assign oxidation numbers to all atoms in the equation.
  9. Explain bond polarity and molecule polarity, and be able to predict their existence in a given molecule.
  10. Identify and explain the different types of intermolecular forces (IMF) including ion..ion, dipole..dipole, H bond, and London forces
  11. Explain how the strength of IMF affects boiling and melting points
  12. Describe different types of solutions, their characteristics, and solubiility
  13. Explain how solubility can be explained through IMF
  14. Explain the difference among solutions, colloids, and suspensions
  15. Explain the difference between electrolytes and nonelectrolytes
  16. Draw "cartoon" structures of simple lipids and use them to explain the solubility properties of lipids in water.
  17. Explain how detergent micelles and bilayers form through IMF.
  18. Define molarity and percent concentration
  19. Know how to make a solution of a given percent concentation or molarity
