Draw real structures
A full chemical editor. Draw the product and Rykie grades the structure itself, not a letter.
For your first organic chemistry course
Organic chemistry,
one question at a time.
Most apps ask you to pick A, B, C or D. Rykie asks you to draw the product, push the arrows, rotate a Newman projection and read an NMR spectrum, and explains every answer.

Not A, B, C or D
You learn chemistry by doing chemistry
Every question is something you would do on paper in an exam, only now it checks you as you go.
Push the curved arrows
Mechanisms the way they are marked: from a lone pair or a bond, to exactly the right atom.
Read real spectra
¹H and ¹³C NMR, IR and mass spectra. Tap the peak, assign the signal, work out the splitting.
Stereochemistry in 3D
Turn Newman projections, flip cyclohexane chairs and tilt Fischer projections under your finger.
Every answer explained
Right or wrong, you see why. The explanation is the part of the question that teaches you.
Answers you can trust
Structures and answers are checked with chemistry software, so what the app marks right really is right.
The course
A path through the whole course
Fourteen chapters in the order you are taught them, from atoms and bonds to spectroscopy. Each session is ten questions: short enough for a bus ride, long enough to stick.
- Basics
- Alkanes
- Stereoisomerism
- Substitution & elimination
- Alkenes
- Alkynes
- Alcohols
- Ethers & epoxides
- Ketones & aldehydes
- Carboxylic acids
- Aromatic compounds
- Conjugated systems
- Amines
- Spectroscopy
More than thirty kinds of question
The questions an exam actually asks
Assign R and S on a Fischer projection. Place the groups on a chair. Balance the equation, rank the acids, pick the reagents for every step of a synthesis. Each kind of question is its own interactive tool, not a picture with four answers underneath.
