UCLA CHEM 14A: Atomic and Molecular Structure, Equilibria, Acids, and Bases
CHEM 14A is the first course in UCLA's general chemistry series for life-science majors and the standard pre-med chemistry entry point. It covers quantum concepts, atomic structure, bonding, equilibrium, and acid-base chemistry on a ten-week clock.

What makes it hard
Starting general chemistry with quantum-mechanical concepts surprises students expecting stoichiometry review, and the equilibrium and acid-base units demand multi-step quantitative fluency by quarter's end. With most of the pre-med cohort enrolled, the curve is competitive and the midterms come fast.
What you'll cover
- • Quantum concepts and atomic structure
- • Electron configurations and periodicity
- • Chemical bonding and molecular shape
- • Chemical equilibrium
- • Acids, bases, and buffers
The CHEM 14A study guide
How to study for UCLA CHEM 14A, step by step.
- 1
Expect quantum, not a stoichiometry review
CHEM 14A opens with quantum-mechanical concepts that surprise students expecting high school chemistry plus. Engage the conceptual material seriously in week one; it's the foundation for bonding and everything after.
- 2
Start problem practice before the first midterm sneaks up
On a ten-week quarter the first exam arrives around week four, before unprepared students have opened the textbook. Daily problems from week one are the only honest preparation.
- 3
Standardize your ICE-table routine
Equilibrium and acid-base problems reward doing the setup identically every time. Build the routine early and it carries you through the quantitative back half of the course.
- 4
Drill your instructor's practice materials
Past exams and practice problem sets from your specific professor are the most exam-representative resources available. Work them timed in the week before each midterm.

FAQ
Is CHEM 14A hard at UCLA?
It's a curved pre-med course on a quarter system, so yes; the pace is the main difficulty. The quantum and bonding material is conceptual while equilibrium is computational, and the exams expect competence in both modes within ten weeks.
What's the difference between CHEM 14A and CHEM 20A?
14A is the life-sciences track (pre-med, biology majors); 20A is the physical-sciences track for chemistry, biochemistry, and engineering majors, with more mathematical depth. Your major determines which series you take; they're not interchangeable without checking requirements.
How do I study for CHEM 14A exams?
Do problems daily rather than rereading notes, and prioritize past exams and practice problem sets from your instructor. Equilibrium and acid-base problems reward a consistent setup routine: ICE tables done the same way every time.

CHEM 20A: Chemical Structure
CHEM 20A opens UCLA's general chemistry sequence for chemistry, biochemistry, and physical-science majors, focusing on quantum theory, atomic and molecular structure, and bonding with more mathematical rigor than the 14-series. It's the physical-science counterpart to CHEM 14A.
CHEM 14B: Thermodynamics, Electrochemistry, Kinetics, and Organic Chemistry
CHEM 14B is the second course in UCLA's general chemistry series for life-science majors and pre-meds, covering chemical equilibria, thermochemistry and the laws of thermodynamics, electrochemistry, chemical kinetics, and an introduction to organic concepts. It follows CHEM 14A on a ten-week clock.
CHEM 14C: Structure of Organic Molecules
CHEM 14C is UCLA's organic chemistry course for life-science majors and pre-meds, covering resonance, stereochemistry, conjugation and aromaticity, and spectroscopy (NMR, IR, and mass spectrometry), with emphasis on biological applications. It follows CHEM 14B and is the pre-med organic gateway.
