UF CHM 2045: General Chemistry 1
CHM 2045 is UF's first general chemistry course, covering stoichiometry, atomic structure, bonding, thermochemistry, and gases. Huge cohorts of pre-health, science, and engineering students take it alongside the CHM 2045L lab, and it's one of the most consequential GPA courses for UF's large pre-med population.

What makes it hard
The exams are multiple-choice, multi-step, and timed, which is a brutal combination: one arithmetic slip in step two of a four-step stoichiometry problem yields a clean wrong answer with no partial credit. The competition is the other factor, since the course is graded against a hall full of pre-meds who treat it as their first audition.
What you'll cover
- • Stoichiometry and limiting reagents
- • Atomic structure and periodic trends
- • Chemical bonding and Lewis structures
- • Molecular geometry (VSEPR)
- • Thermochemistry
- • Gas laws
The CHM 2045 study guide
How to study for UF CHM 2045, step by step.
- 1
Get mole math automatic in three weeks
Stoichiometric fluency gates everything after it in CHM 2045. Daily conversions until they're reflexive is the single best early investment.
- 2
Memorize ions and rules before exam one
Flashcard polyatomic ions, solubility rules, and nomenclature early so exam minutes go to multi-step reasoning instead of recall.
- 3
Train under the clock
Timed multiple choice with no partial credit means speed and accuracy are the whole grade. Practice problems on a timer, every time.
- 4
Classify every miss
Tag each miss as a concept gap, a setup error, or an arithmetic slip. Each needs a different fix, and untagged misses get re-made on exam night.

FAQ
Is CHM 2045 a weed-out class at UF?
It functions like one, especially for pre-meds. The material is standard gen chem, but timed multiple-choice exams with no partial credit and a competitive curve mean small errors are expensive. Weekly problem volume is the difference-maker.
How do I study for CHM 2045 exams?
Work practice exams timed, and review every miss by category: concept gap, setup error, or arithmetic. Memorize polyatomic ions and solubility rules early so exam time goes to multi-step reasoning rather than recall.
Do I take CHM 2045L at the same time?
Most students take the lab concurrently since downstream courses and pre-health requirements expect both. The lab is a separate grade and a separate time commitment, so budget for the reports when planning your week.

CHM 2046: General Chemistry 2
CHM 2046 is UF's second general chemistry course, covering kinetics, equilibrium, acids and bases, thermodynamics, and electrochemistry. Huge cohorts of pre-health, science, and engineering students take it with the CHM 2046L lab, and it continues the gen-chem sequence that gates organic chemistry and the pre-med track.
CHM 2210: Organic Chemistry 1
CHM 2210 is UF's first organic chemistry course, covering structure, bonding, stereochemistry, and the reaction mechanisms of substitution and elimination. Pre-med and science majors take it after the general chemistry sequence. It's one of the most consequential courses on the pre-health track and runs in large lecture sections.
