Required materials (You will be turned away and earn a zero in attendance for missing safety attire!):
- The book
- Goggles (not safety glasses) A seal should form around your eyes.
- Pants (not shorts) Your legs must be covered.
- Shoes (not sandals) Your feet must be completely covered.
- A lab coat
What you should be learning:
- Know the dangers of each laboratory including how to mitigate your risk.
- Read and understand all the chapter and not just the experimental procedure.
- Make sure that you can draw all structures and mechanisms for each lab.
- Be able to apply a given mechanism to other reagents because we are not just cooks!
- Understand which fundamental mechanism you are applying (Addition, Elimination or Substitution) including the stereochemical consequences.
- Understand whether a reaction is an oxidation, reduction or not a net redox reaction.
- Be able to calculate the yield of a
reaction.
- structure to formula conversion,
- formula to molecular weight conversion,
- ml to grams via density and vice-versa,
- grams to moles,
- what is the limiting reagents,
- what is the stoichiometry of the reaction.
- Understand why a particular procedure was followed.
Your grade will consist of:
- 1/3 attendance. You must participate fully in the lab, and not come and go as you please!
- 1/3 laboratory Quizzes. Quizzes will be open only on the Monday of the given lab week.
- 1/3 laboratory Reports. Reports will open on the Friday morning after the lab and close at 11:59 pm of the next Monday.
