UMD CHEM 231: Organic Chemistry I
CHEM 231 is UMD's first organic chemistry course — structure, stereochemistry, reaction mechanisms, and substitution and elimination chemistry — the storied pre-health filter taken after the general chemistry sequence.
Fennie is independent and not affiliated with University of Maryland. This is an unofficial study guide.
Build my CHEM 231 study planWhat makes it hard
Orgo punishes the memorization strategy that survived general chemistry: the reaction space is too large to memorize, and exams ask you to predict products and draw mechanisms for combinations you haven't seen. Students who learn electron-pushing logic find it learnable; students who flashcard reactions individually drown by mid-semester.
What you'll cover
- • Structure, bonding, and resonance
- • Stereochemistry
- • Acid-base chemistry
- • Substitution and elimination reactions
- • Reaction mechanisms and electron pushing
- • Spectroscopy basics
The CHEM 231 study guide
How to study for UMD CHEM 231, step by step.
- 1
Learn mechanisms, not reaction lists
The course is a logic system: nucleophiles attack electrophiles for reasons. Learn the electron-pushing logic of each mechanism class and whole families of reactions become predictable instead of memorizable.
- 2
Draw every day
Structures, resonance arrows, mechanisms — orgo is a paper skill and daily drawing is non-negotiable. Reading the textbook recognizes chemistry; drawing it produces chemistry, and exams grade production.
- 3
Master stereochemistry early and physically
Chirality and spatial reasoning underwrite the entire substitution/elimination story. Use models or systematic drawing conventions until R/S assignments and inversions are automatic.
- 4
Practice predict-the-product on novel combinations
Exams present substrate-reagent pairs you haven't seen and grade your reasoning. Practice on unfamiliar combinations weekly — familiar-example review builds false confidence.

How Fennie helps with CHEM 231
Fennie's Daily Plans space CHEM 231's mechanism practice daily — the only schedule organic chemistry's volume responds to — with cumulative review built in because orgo never stops testing chapter one. Chat through why a mechanism proceeds the way it does until the electron-pushing logic replaces the memorization strategy that fails here.
FAQ
Is CHEM 231 at UMD as hard as people say?
Its filter reputation is earned, but the failure mode is specific: memorizing reactions individually instead of learning mechanism logic. Students who practice electron pushing daily and review cumulatively find it demanding but systematic.
How should I study for organic chemistry?
Draw daily — mechanisms, resonance, stereochemistry — and practice predicting products for substrate-reagent combinations you haven't seen. Understand why each mechanism proceeds; the reaction space is far too large to memorize entry by entry.
How do I prepare for CHEM 231 before it starts?
Sharpen the general chemistry foundations orgo assumes: acid-base reasoning, Lewis structures, and resonance. Comfort with those three lets you spend the semester on mechanisms instead of remediation.
