CHEM V12BL
IV. COURSE OBJECTIVES:
1. Students will demonstrate their advanced knowledge of methods of synthesis and
purification by preparing isoamyl acetate, methyl orange, triphenylmethanol, N,N-diethyl-mtoluamide, 5-n-butylbaraituric acid, tetraphenylcyclopentadienone and various polymers.
2. Students will demonstrate their ability to keep accurate records by maintaining a
notebook and submitting laboratory reports.
3. Students will demonstrate their understanding of organic laboratory techniques and nmr
and IR by identifying three separate organic unknowns and a mixture of two organic unknowns.
