This class is an introduction to organic chemistry. The objectives of this class are to master fundamental organic
chemistry concepts.
Chapter 1
-Review definitions – atom, covalent bonds, polar bonds, electron configuration, wavefunction, valence
electrons.
-Construct Lewis Structures, bonding and nonbonding electrons.
-Valence bond theory, sigma bonds and pi bonds.
-Hybridization of s and p orbitals.
-Molecular Orbital Theory, bonding MO and antibonding MO.
Chapter 2
-Review the electronegativity trend using the Periodic Table.
-Predict polar covalent bonds, dipole moments, and formal charges.
- Understand the concept of resonance forms, rank the importance of various resonance forms, and
draw each of the resonance form.
-Review Bronsted-Lowry acid/base chemistry; predict acid-base reactions from pKa values.
-Lewis acid/base chemistry.
-Drawing chemical structures.
Chapter 3
-Overview on classification by functional groups; carbon-carbon multiple bonds, carbon singly bonded to
an electronegative atom, carbonyl groups
-Define and identify constitutional isomers.
-Name alkanes and cycloalkanes.
-Understand the basic physical and chemical properties of alkanes and cycloalkanes.
Chapter 4
-Understand how different conformational isomers have different energies. Predict high and low energies
by using energy cost such as torsional, steric, and angle strains.
-Special attention will be spent on the conformation of cyclohexane. Predicting most stable conformation
by using the torsional and steric strains.
-Overview on conformational polycylic molecules.
Chapter 5
-Overview of basic organic reactions, addition, elimination, substitution, and rearrangement reactions.
-Define reaction mechanism and the types of bond cleavage.
-Overview on radical reactions and its steps, initiation, propagation, and termination.
-Overview on polar reactions and be able to predict the nucleophile and electrophile
-Chemical reactions can be described through equilibria, rates and energy changes. Equilibria, kinetic and
bond dissociation equations will be reviewed. Interpreting and creating energy diagrams.
Chapter 6
-Structure and reactivity of alkenes will be discussed. Review basic sp2 hybridization.
-Calculating a molecules degree of unsaturation.
-Learn the alkene nomenclature including cis/trans and E/Z designation of isomers.
-Predict the stabilities of substituted alkanes.
-The mechanism of electrophilic additions of HX to alkenes will be review. This reaction is regiospecific
and uses Markovnikov’s Rule. Hammond postulate and carbocation rearrangement also be introduced at
this time.
Chapter 7
-Study the alkene reactions. Use concepts such as molecular geometry and polarity to predict reaction
products.
-Alkene-forming elimination reaction – dehydrohalogenation and dehydrations
-Study the alkene addition reactions. This will include basic reactions such as addition of halogens,
halohydrin formation, oxymercuration, hydroboration, carbenes
-Learn the reaction mechanism for reduction, oxidation, cleavage of alkenes.
-Learn the reaction mechanism for the addition of radicals to alkenes.
Chapter 8
-Review the structure of alkynes.
-Learn how to name alkynes.
-Study the reaction mechanism of the elimination of dihalides to make alkynes.
-Study the alkene reactions such as the addition of HX and X2, hydration, reduction, and oxidative cleavage.
-Use acid/base chemistry to form the acetylide anion for alkylation.
-Introduction to synthesis. This is a great way to reinforce all of the chemical reactions you have learned.
Chapter 9
-Stereochemistry is the study of handedness. Define enatiomers, chirality and optical activity.
-Learn how to assign chiral center the proper rotational configuration. R or S instead of right or -left,
respectively.
Chapter 10
-Review how to name alkyl halides.
-Use periodic trends to predict bond length, strength, and dipole-moment.
-Review, electrophic addition reactions and radial addition of halogens, and apply the Hammond postulate
to predict reaction rates and product yield.
-Determine if an organic reaction is oxidation, reduction or neither.
Chapter 11
-Able to predict if a nucleophilic substation is (Sn2, Sn1, E2 or E1). In order to determine which
mechanism, the student must be able to evaluate the steric effects of the alkyl halide, strength of the
nucleophile (nucleophilicity), the readiness of the leaving group, and solvent charactersics.
-Must be able to apply Zaitsev’s Rule to elimination reactions.
-Predict products the stereochemistry of a nucleophilic type reaction.
Chapter 12 and 13
-Known what mass, infra red (IR), Nuclear Magnetic Spectroscopy (NMR) spectrometries measure and the
basic concepts which they work.
-Interpret spectra.

Lab Rules and Safety. WEAR YOUR SAFETY GOGGLES IN THE LAB AT ALL TIMES. You should also wear
your gloves and aprons while handling chemicals. You must comply with the safety rules posted in the lab; repeated
violation of these rules may result in expulsion from the course with a grade of F. Do not carry out any unassigned
experiment or project without written authorization by the instructor. Laboratory work is to be performed during
scheduled lab periods only (see the instructor for information about making up labs). The prep room and chemical
storage area are off limits to students, except authorized laboratory assistants.
Preparations. YOU MUST TURN IN THE SPECIFIED PRODUCT FROM EACH EXPERIMENT. Each product
listed in the lab schedule should be submitted to the instructor on or before the due date for the experiment.
Lab Reports. Turn in each lab report on the form provided on or before the due date attaches any required graphs or
spectra. Reports must include answers to the assigned exercises. Late reports are penalized 3 points if turned in
within a week after the due date, 10 points thereafter.

Disability Services and Accommodations for Students. In compliance with Lake Superior State University policy
and equal access laws, disability-related accommodations or services are available. Students who desire such
services are to meet with the professor in a timely manner, preferably the first week of class, to discuss their
disability-related needs. Students will not receive services until they register with the Resource Center for Students
with Disabilities (RCSD). Proper registration will enable the RCSD to verify the disability and determine reasonable
academic accommodations. RCSD is located in South Hall Office 206. The telephone number is (906) 635-2454.
Academic Misconduct: Scholastic misconduct is cause for a failing grade, and I reserve the right to place a letter
about the incident in the student’s permanent file in the Office of Academic Affairs. Scholastic dishonesty includes,
but is not limited to, cheating on assignments or examinations, plagiarizing, misrepresenting as your own work any
part of work done by another, or interfering with another student’s work.
Finally, this syllabus is my best estimate of the topics we will cover. I reserve the
right to modify this syllabus as I see fit during the course of the semester.
