Catalog Course Description
A course in organic chemistry including the properties and reactions of aromatic compounds, aldehydes, ketones, carboxylic acid derivatives, enols, enolates, amines, NMR. Second semester course required for students in pre-professional programs in medicine, dentistry, pharmacy, veterinary science, biology, and chemistry. CHEM 221L is required concurrently for most of the stated majors. 54 lecture hours.
Course Objectives
- Name Alcohols, Phenols, Ethers, Epoxides, Thiols, Aromatic Compounds, Aldehydes and Ketones, Carboxylic Acids and their Derivatives, Amines and determine their physical properties, and their chemical reactions.
- Predict the reactions of conjugated Pi Systems and Pericyclic Reactions, Alpha Carbon Chemistry, Enols and Enolates. predict thermodynamic control vs liketic control, Diels-Alder reactions. Alpha halogenation of enols and enolates, aldol reaction, Claisen condensations, conjugated addition reactions.
- Determine the structure of an organic compound from the number of signals, the area under each peak, the multiplicity of each peak, and the location of each signal (peak) by analyzing NMR spectroscopy.
- Solve a problem such as: give an organic compound which has two functional groups an aldehyde and a ketone. the objective is to reduce the ketone while leaving the aldehyde untouched. The aldehyde fuctional group must be blocked by a chemical recation. The ketone will be reduced. The aldehyde will be converted back using acid hydrolysis.
Major Course Content

None
Examples of Required Writing Assignments
Extra credit assignment. Homework. NMR problems.
Examples of Outside Assignments
Extra credit assignments such as explaining Hammond Postulate which requires an E-diagram to be drawn to show Energy va Reaction Coordinate. The shape of the graph will indicate whether the intermediate look more like reactant or product. Therefore the stability and the structure of the intermediate can be discussed. The choice of solvent in this case can be critical as which side of the reaction would be stabilized.
