Final Quiz Review Sheet - 3321
Bring your Molecular Models and a calculator.
The final quiz is closed book.
The final quiz will consist mostly of Prelab quiz type multiple choice questions. The following topics will be covered:
- Lab Manual introduction paragraphs in each experiment in the 3321 Lab Manual.
- Lab Handbook assigned reading.
- Study Questions ("Extra Study Questions" will not be covered)
- Procedures. You need to know the purpose of organic chemistry techniques in a work-up scheme, including crystallization, distillation, extraction, washing steps (saturated aqueous NaCl, saturated aqueous NaHCO3), and drying agents.
You do not have to memorize: physical properties of reagents; procedures and glassware set-ups for each specific experiment; the exact procedure for each experiment or the hazards of specific reagents.
- Calculations of moles of reagents and theoretical yield.
- You need to know the names of the glassware and equipment in your lab drawer.
- Modeling exercises I (Conformational Analysis of Alkanes and Cyclohexanes) and II (Stereochemistry). You need to know how to draw Newman projections, indicate eclipsed bonds or gauche interactions, designate a molecule as R or S, and determine if given molecules are enantiomers or diastereomers.
- IR Spectroscopy. Be able to tell whether an IR spectrum is of an amine, alcohol, carbonyl, alkane, or alkene. Memorize the following IR stretching frequencies, since you will not be given a table of stretching frequencies for the final quiz.
3500-3300 cm-1 N–H stretch 1°, 2° amines
3500-3200 cm-1 O–H stretch alcohols, a broad, strong band
3100-3000 cm-1 C–H stretch alkenes
3000-2850 cm-1 C–H stretch alkanes
1760-1665 cm-1 C=O stretch ketones, aldehydes, esters
1680-1640 cm-1 C=C stretch alkenes
