IU CHEM-C 117: Principles of Chemistry and Biochemistry I

C117 is IU's distinctive first chemistry course for science and pre-health majors — general chemistry principles integrated with biochemistry from the start, rather than the traditional gen-chem-only opener. It anchors the chemistry sequence and carries a serious workload reputation.

Fennie is independent and not affiliated with Indiana University Bloomington. This is an unofficial study guide.

What makes it hard

The integration is the difficulty multiplier: you're learning general chemistry's quantitative core while simultaneously applying it to biomolecules, so there's no easy memorization lane. Exams are time-pressured and problem-based in a pre-med-heavy room, and students who follow lecture without daily problem work get their correction on exam one.

What you'll cover

  • Atomic structure and bonding
  • Stoichiometry and reactions
  • Thermodynamics basics
  • Intermolecular forces
  • Biomolecule structure and function
  • Equilibrium concepts

The CHEM-C 117 study guide

How to study for IU CHEM-C 117, step by step.

  1. 1

    Make the quantitative core automatic early

    Stoichiometry and equilibrium reasoning are embedded in everything C117 does, including the biochemistry. Drill the calculations daily until they cost no thought.

  2. 2

    Work problems cold every day

    Following lecture while practicing little is the classic setup for an exam-one shock in a pre-med-heavy room. Solve daily with solutions closed and redo every miss.

  3. 3

    Learn structures as logic, not flashcard images

    The biomolecule material rewards understanding why a structure behaves as it does — polarity, bonding, interactions — over raw memorization. The exam questions connect structure to chemistry deliberately.

  4. 4

    Connect the two halves constantly

    C117's whole design is general chemistry applied to biological molecules. When a concept appears in both contexts, study it as one idea — the integrated questions are where exams separate students.

  5. 5

    Run timed practice before each exam

    Time-pressured problem exams reward trained speed. Mixed sets under exam timing in the final week beat another pass through the notes.

How Fennie helps with CHEM-C 117

Fennie's Daily Plans make C117's integrated load survivable — daily problem work from week one, structure review spaced across units, everything paced to exam dates. Chat unpacks why a biomolecule behaves the way its chemistry says it must, the connective reasoning this course's exams grade.

FAQ

Is C117 at IU hard?

It has a deserved reputation: general chemistry's quantitative core and biochemistry's structural material at once, with timed problem-based exams in a pre-med-heavy room. Daily problem practice handles it; lecture-following alone visibly doesn't.

How is C117 different from regular general chemistry?

IU integrates biochemistry from the start instead of saving it for later courses — you apply gen-chem principles to biomolecules immediately. It suits the pre-health pipeline but means there's no pure-memorization lane through the course.

How do I pass C117?

Make the calculations automatic early, work problems cold daily, and study structures as chemistry rather than images to memorize. Then run timed mixed practice before each exam — speed is part of what's tested.
