D867 Organic Chemistry, catalog number CHEM 3010, is the three-CU course on carbon-based chemistry for teacher candidates, covering nomenclature, the processes molecules undergo and the instrumental methods used to work out what a molecule is. Its reputation for difficulty comes from students trying to memorise it. Organic chemistry has fewer principles than general chemistry and far more consequences, and the students who do well spend their time on why electrons move rather than on lists of reactions.
Electrons move from rich to poor
Almost every organic reaction is one sentence in different clothing: a region of high electron density attacks a region of low electron density, and something leaves. Learning which parts of a molecule are electron rich, lone pairs, double bonds, negatively charged centres, and which are electron poor, carbons bonded to electronegative atoms, positively charged centres, converts a catalogue of reactions into a small set of moves. Curved arrows are the notation for that movement, and drawing them correctly is a skill worth practising deliberately because it also prevents most mechanism errors.
Structure determines behaviour, and structure means three dimensions. Molecules with identical formulas can differ in connectivity or in arrangement in space, and those differences change reactivity and biological effect entirely. Students who never build or draw three-dimensional representations find stereochemistry impenetrable; students who do find it mechanical. If you have access to a model kit, it repays its cost in the first fortnight, and paper drawings with wedges and dashes work almost as well when practised.
Instrumental analysis closes the loop, and it is where the course becomes genuinely satisfying. Infrared absorption reveals which functional groups are present, mass spectrometry gives molecular mass and fragmentation clues, and nuclear magnetic resonance reports on the environments of particular nuclei and how many neighbours each has. Given those three sets of evidence, a structure can be deduced rather than guessed, and deduction from spectra is a common assessment task precisely because it requires everything else in the course.
Planning the work from your Course of Study
The scoring detail sits in your Course of Study rather than in the public catalog. Read it early, because an organic course assessed by written work and one assessed by a proctored objective assessment demand different practice, and both demand more drawing than reading. Each aspect is judged alone and needs a 2, so a strong nomenclature section cannot compensate for a mechanism section that skipped the arrows.
The word budget, worked. Suppose five scored aspects and directions asking for about 1,500 words alongside any structures you supply. Reserve 100 words to frame the compound or reaction and 90 for a close, leaving roughly 1,310, or 260 an aspect. Then rebalance: the mechanism aspect and the spectral interpretation aspect each take an extra 60 words, taken from the descriptive sections. Structures and spectra carry meaning that prose cannot, so every drawing needs a caption and one sentence saying what it demonstrates.
The study budget, worked. Fifty hours across three competency units, and the allocation is unusual. Ten hours on nomenclature and functional group recognition until both are automatic, ten on structure and stereochemistry with models or drawings, fifteen on mechanism practice with arrows drawn every time, ten on spectral interpretation with real spectra, and five on mixed problems. Reading time inside those blocks should be small; this is a subject learned with a pencil.
The pace trap is specific. Organic chemistry punishes gaps more than any other undergraduate chemistry course, because each mechanism assumes the last. Falling three days behind is recoverable; falling three weeks behind usually means restarting.
A structure that fits an organic chemistry deliverable
Where the task directions prescribe a format, follow it. Where they do not, this arrangement suits a structure determination or reaction analysis.
| Section | What belongs in it | What earns the aspect |
|---|---|---|
| Compound and context | What the molecule is, or what evidence you were given about it | Frames the deduction that follows |
| Nomenclature | Systematic name with the numbering and priority rules applied | Scored for correct application, not for the name alone |
| Structure | The drawing, including stereochemistry where it matters | Scored for representation quality; ambiguous drawings cost aspects |
| Mechanism | Arrows showing electron movement, step by step, with intermediates | The aspect that separates understanding from recall |
| Spectral evidence | Each spectrum read for what it rules in and rules out | Scored for reasoning from data rather than reporting peaks |
| Deduction | How the evidence converges on one structure | Scored for the argument, which is what the exercise is for |
| Alternatives excluded | Candidate structures considered and why they fail | Frequently the difference between adequate and convincing |
| Sources | Reference data, spectral tables and any published values, APA | Scored where citation is named |
Number your structures and refer to them by number in the text. Organic writing becomes unreadable quickly when every reference is a verbal description of a molecule, and unreadable writing loses aspects it had the content to satisfy.
Evidence craft when the evidence is a spectrum
Spectral interpretation is an argument, and the argument has to be visible.
- State what each piece of evidence rules out as well as what it suggests. An absorption band absent is often more informative than one present.
- Quote positions and values with the units and the reference used, and cite the table you compared against.
- Account for all major features. A peak you cannot explain is a signal that your proposed structure is wrong, and ignoring it is what evaluators look for.
- Use integration and splitting information explicitly where you have it, since counts of neighbouring nuclei are the strongest constraints available.
- Keep drawings unambiguous: correct bond angles, explicit stereochemistry, and no carbon left with the wrong number of bonds.
- Distinguish what you deduced from what you assumed, particularly where you relied on how a compound was made.
- Cite spectral reference data and any software or database used, in APA where directions require it.
Where a mechanism is asked for, draw every step rather than jumping to the product. Intermediates are frequently the scored content, and a mechanism with a missing step reads as a memorised outcome rather than as reasoning.
What separates Competent from a return or a retake
Aspects score independently, and organic returns usually name mechanism or spectral reasoning rather than knowledge.
- Arrows start at electron density and end where electrons go.
- Every mechanism step is shown, including intermediates and charges.
- Stereochemistry is drawn where it changes the answer.
- Spectral features are all accounted for, not just the convenient ones.
- The deduction states what alternatives were excluded and why.
- Names and structures agree with each other throughout.
Performance assessment work at WGU can be revised and resubmitted without a grade penalty, so a return costs time rather than standing. In a six-month flat-rate term, organic chemistry is the course where falling behind is most expensive, because the material compounds. Where any part of the course is assessed by a proctored objective assessment, we prepare only, never sit it and never ask for portal credentials.
Six mistakes that cost time in D867
- Memorising reactions. There are hundreds of reactions and about a dozen electron movements, and only one of those lists is learnable.
- Drawing arrows backwards. Electrons move from rich to poor, and reversed arrows signal a misunderstanding rather than a slip.
- Ignoring three dimensions. Stereochemistry decides outcomes, and flat thinking makes an entire strand of the course impossible.
- Reading spectra as lists. A spectrum is evidence in an argument, and reporting peaks without deduction earns nothing.
- Skipping nomenclature. It is the language of the subject, and every later communication error traces back to it.
- Studying by reading. This subject is learned by drawing, and no amount of reading substitutes for a hundred mechanisms drawn by hand.
How support works on this course
Send your topic list or task directions with the scoring detail from your Course of Study. What comes back is mechanism practice with the arrows explained rather than presented, a spectral interpretation method you can apply to an unfamiliar compound, and structure work that makes stereochemistry visible instead of abstract.
Where a written deliverable is involved, we build the deduction as an argument: evidence, what it excludes, what remains, and why the final structure is the only one that fits everything.
The most common single request on this course is help catching up after a lost fortnight. That is worth asking for early, because organic chemistry is the subject where the cost of delay grows fastest.

The assessments, one by one
The public catalog does not publish this course's PA/OA identity or task count. WGU Tutors publishes at most one PA manual per course and only from a WGU-controlled public rubric. Until that source exists, PA help begins from the student's real Course of Study and OA support remains preparation only.
