UNC CHEM 101: General Descriptive Chemistry I
CHEM 101 is UNC's first general chemistry course: stoichiometry, atomic structure, periodicity, bonding, and thermochemistry. It's the opening gate of the pre-health and science sequences, taken in large lectures with the lab (CHEM 101L) as a separate course.

What makes it hard
Time-pressured multi-step exams in a room dense with pre-meds: stoichiometric fluency is assumed from the early weeks, and partial understanding that survives homework collapses under exam conditions. The classic casualty followed lecture comfortably, did each problem once, and learned at exam one that recognition and production are different skills.
What you'll cover
- • Stoichiometry and the mole
- • Atomic structure and periodicity
- • Chemical bonding and molecular geometry
- • Thermochemistry
- • Gas laws
- • Solution chemistry basics
The CHEM 101 study guide
How to study for UNC CHEM 101, step by step.
- 1
Automate stoichiometry in the first three weeks
Mole conversions and reaction stoichiometry are embedded in everything CHEM 101 does afterward. Drill daily until they cost nothing; slowness here bleeds exam points all semester.
- 2
Solve problems cold every day
Following lecture while practicing little is the standard setup for an exam-one shock. Work problems with solutions closed daily and redo every miss the next day.
- 3
Let units steer the long problems
Write units on every quantity and make them cancel. Dimensional analysis converts multi-step calculation chains from memory tests into guided paths, and it catches errors before the grader does.
- 4
Practice the conceptual questions too
Periodicity, bonding, and geometry questions test trends and reasoning: why this radius is larger, why this shape. Explaining the why aloud is cheap practice for the multiple-choice points students quietly lose.
- 5
Train under time before each exam
Mixed exam-style problems, timed, no notes. The room is full of pre-meds doing exactly this; speed with accuracy is the actual tested quantity, and homework pace never measures it.

FAQ
Is CHEM 101 at UNC a weed-out class?
It functions as the pre-health track's first filter: time-pressured multi-step exams in a pre-med-dense room set a high effective bar. Daily problem practice beats it reliably; comfortable lecture-following without production practice reliably doesn't.
How do I pass CHEM 101?
Make stoichiometry automatic in the first three weeks, solve problems cold daily, and rework every miss. Before each exam, do mixed problems timed and without notes; exam speed is a trained skill that homework alone doesn't train.
Do I take CHEM 101L at the same time?
The lab is a separate one-credit course usually taken alongside. Pre-health and science-major paths care about the lab sequence, and it adds a steady weekly time cost, so plan for it rather than discovering it.

CHEM 102: General Descriptive Chemistry II
CHEM 102 completes UNC's general chemistry pair: kinetics, equilibrium, acids and bases, thermodynamics, and electrochemistry, with the lab (CHEM 102L) separate. It's the direct gatekeeper to organic chemistry and the course where gen chem turns conceptual.
CHEM 261: Introduction to Organic Chemistry I
CHEM 261 is UNC's first organic chemistry course: structure and bonding, stereochemistry, substitution and elimination, and the beginnings of reaction mechanisms. It's the most mythologized course on the pre-health track, with exams that reward reasoning over recall.
