OrgoMech: O-Chem Predictor
Reactions, Mechanisms & Plan
OrgoMech turns confusing reactions into clear, visual answers. Build a reactant, choose your reagents, and instantly see the major and minor products — plus the full electron-pushing mechanism, arrow by arrow.
Whether you are prepping for a midterm, your final, or the MCAT, OrgoMech helps you stop memorizing blindly and start understanding how reactions actually work — the exact arrow-pushing your professor wants to see on the exam.
Predict products fast: draw a molecule or pick a template, add reagents, and get the reaction. See every mechanism step-by-step. Learn the why — key points, major vs. minor products, and yields. Browse a reaction library: SN1/SN2, E1/E2, additions, carbonyls, aromatics, redox, and more. Study smarter with a personalized plan that counts down to your final.
OrgoMech Pro is an auto-renewable subscription for full access: weekly or yearly (price shown in the App Store). Payment charged to your Apple ID at confirmation. Renews unless canceled at least 24 hours before the period ends. Manage in Settings → Apple ID → Subscriptions.

Frequently asked questions
Is OrgoMech a homework answer key?
No. It is a study tool to predict products and learn mechanisms. Use it to understand reactions — not to skip the work your course requires.
Does OrgoMech require a subscription?
Full access uses OrgoMech Pro (auto-renewable weekly or yearly). Prices shown in the App Store. Cancel in Apple ID → Subscriptions at least 24 hours before renewal.
Does it cover SN1, SN2, E1, and E2?
Yes — plus additions, carbonyls, aromatics, redox, and more in the reaction library, each with reagents, conditions, products, and mechanisms.
