Organic Chemistry Lab 3D

Organic Chemistry Lab — Learn in 3D Organic chemistry is three-dimensional, and a flat page cannot show you why. Why a hydrogen has to be anti-periplanar before it will eliminate. Why a carbocation loses all memory of which face the leaving group was on. Which of two mirror images you are actually looking at. So turn the molecule instead. FOUR INSTRUMENTS • Conformation Lab — drag a bond and watch the Newman projection turn with it while the energy curve follows. See butane's gauche cost appear as steric strain while the torsional part stays flat. Analyse a cyclohexane chair, find the axial groups, and watch the ring flip decide which chair wins. • Chirality Lab — commit to R or S before the priorities are shown, then turn the model to check yourself. Put a molecule beside its mirror image and try, with your own fingers, to superimpose them. • Reaction Bench — set the substrate, the reagent, the solvent and the temperature. Predict whether SN1, SN2, E1 or E2 wins. Then run it, and watch the nucleophile arrive at 180° from the leaving group while the carbon turns inside out. • Spectra Lab — identify a compound from its ¹H NMR, IR and mass spectrum, the way a problem set asks you to. SIX UNITS, 41 LESSONS 1. Structure & Bonding — hybridisation, skeletal structures, functional groups, pKa 2. Naming & Conformation — IUPAC names, Newman projections, ring strain, the chair 3. Stereochemistry — chirality, CIP priorities, R/S, diastereomers, meso, E/Z 4. Substitution & Elimination — leaving groups, the SN1/SN2/E1/E2 grid, solvent effects 5. Alkenes & Alkynes — Markovnikov and why, anti and syn additions, ozonolysis 6. Aromatics, Carbonyls & Spectra — aromaticity, directing effects, C=O, IR, NMR, elucidation NOTHING IS GUESSED Every shape, angle, energy, R/S label, IUPAC name, mechanism verdict and predicted spectrum is computed on your device by the app's own chemistry engine — not looked up from a table of pre-written answers. Methane comes out at 109.5° because the rule was applied, and the cyclohexane chair keeps both its tetrahedral angles and its 1.54 Å bonds because that is what a chair is. Which also means it all works offline. On a train, in a basement library, with no signal at all. ONE NARROW AI FEATURE A button that explains, in words, why the answer is the answer. It is never asked what the answer IS — the engine has already decided that, and the model only phrases it. A fluent wrong answer is indistinguishable from a right one to the person who most needs the right one. FREE, AND HONESTLY SO Unit 1 in full, the first lesson of every other unit, all four labs with no restrictions, the entire 54-molecule library, and three AI explanations a day — free. Pro adds the remaining 35 lessons, unlimited explanations, and removes ads. The paywall is skippable everywhere it appears. Note: the NMR, IR and mass spectra are predicted from standard correlation tables rather than recorded on an instrument, and the app says so where they appear. They are reliable for what structure elucidation depends on — signal count, splitting, integration, which carbonyl — and approximate in the second decimal of a shift. FOR Anyone taking a first or second organic chemistry course — high school, university, or exam preparation — and anyone who once found the subject impossible on paper and suspects it might not be in three dimensions. WHAT IS FREE All four labs stay open to everyone — Conformation, Chirality, the Reaction Bench and Spectra. So do 11 of the 41 lessons: the whole of Unit 1, plus the first lesson of every unit after it. Pro adds the remaining 30 lessons and unlimited AI explanations, and removes the ads. It is offered monthly or yearly. Privacy Policy https://coddykit.com/terms/privacy-policy
