Rykie - Organic Chemistry

Most chemistry apps ask you to pick A, B, C or D. Rykie asks you to do organic chemistry: draw the product, push the curved arrows, turn a Newman projection, assign R and S, and read an NMR spectrum. 4,500+ organic chemistry questions across 14 chapters and 11 practice drills, with every answer explained. Learn by doing, not by guessing • Draw structures in a real chemical editor, graded on the molecule you drew, not on the picture • Push curved arrows through reaction mechanisms, step by step • Rotate Newman projections, flip cyclohexane chairs and read Fischer projections • Tap the peak, match the spectrum: IR, mass spectrometry, proton NMR and carbon-13 NMR • Balance equations, order by acidity, sort nucleophiles from electrophiles, place a pKa on the scale • 30+ kinds of question, so a session never turns into a multiple-choice quiz A path through the whole course Fourteen chapters in the order organic chemistry is usually taught, each built from short 10-question sessions you can finish on a bus ride: Basics · Alkanes · Stereoisomerism · Nucleophilic substitution and elimination · Alkenes · Alkynes · Alcohols · Ethers and epoxides · Ketones and aldehydes · Carboxylic acids · Aromatic compounds · Conjugated systems · Amines · Spectroscopy Every answer explained Get something wrong and Rykie shows you what the right answer was and why: the missing lone pair, the carbocation that rearranged, the proton that splits the signal. Review sessions mix earlier questions back in, so what you learned stays learned. Practice drills for the skills that decide an exam • Naming compounds and drawing compounds from their names • Predict the product and multistep synthesis • R and S, hybridization, Lewis structures and resonance • Nucleophiles and electrophiles, acids, bases and equilibria • Same compound, isomer or conformer? Cheat sheets that move Animated SN1, SN2, E1 and E2 mechanisms, hydride and methyl shifts, a ring flip you can watch, a pH slider, a decision tree for substitution versus elimination, and every reagent in the course on one set of illustrated reaction cards.
