Chemistry
CHM 213: Organic Chemistry Laboratory I (1)
Learning Objectives:
This is a basic organic chemistry practical course. In this laboratory course, students would be able to use their knowledge of chemical reactivity to plan and execute the preparation of compounds using various C-C and C-hetero bond-forming reactions and various organic transformations from commercially available starting materials. Upon completion of this laboratory course, the students would also get confidence on working independently and characterize the synthesized compounds using various modern techniques.
Suggested Experiments:
- Calibration of melting point apparatus thermometer
- Hydrolysis of ester: Preparation of salicylic acid from methyl salicylate
- Etherification of alcohol: Preparation of 2-ethoxynaphthalene
- Preparation of amide: Synthesis of acetanilide from aniline
- Oxidation of olefin with KMnO4: Preparation of adipic acid from cyclohexene
- Reduction of ketone: Preparation of benzhydrol by NaBH4 reduction of benzophenone
- Aldol reaction: Preparation of dibenzylideneacetone
- Electrophilic aromatic substitution: Nitration of acetanilide
- Nucleophilic substitution reactions: The effect of substrate structure on the reactivity under SN1 and SN2 conditions
- Preparation of pyridinium chlorochromate (PCC)
- Beckmann rearrangement: Preparation of benzanilide from benzophenone oxime
- Esterification of an aromatic acid.
- Synthesis of an azo-dye.
- Dakin oxidation of an aromatic aldehyde.
