Organic Chemistry: OrgoMech
Reaction Mechanism MCAT Tutor
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Predict the major product, then order the curved arrows. Organic chemistry practice for reactions, mechanisms, and the days left before your final.
Organic chemistry reactions, with the mechanism your exam actually asks for.
OrgoMech shows the major product of your molecule, then the curved arrows in order. Draw a reactant or start from a template, add the reagents, and see why that product wins.
WHY PRE-MEDS USE ORGOMECH
• Predict the product — your structure, the regiochemistry, and the stereochemistry
• Practice the mechanism — put the electron-pushing steps in the right order
• Daily exam drill — missed reactions come back until both parts are right
• Reaction library — substitution, elimination, addition, carbonyls, aromatics, and redox
• Countdown to the final — the drill sits on Home with the days you have left
BUILT FOR THE EXAM
Use it for a midterm, the final, or the organic chemistry section of the MCAT. Each reaction explains the product that wins, including the trap answers students mix up.
MASTER THE MECHANISMS
Watch the nucleophile attack, the leaving group leave, and the pi bond form. That is the arrow-pushing a graded mechanism asks you to show.
A REACTION LIBRARY THAT MAKES SENSE
Browse the core reactions by type. Each one includes the reagents, the conditions, the products, the mechanism, and the point that gets tested.

What's New
• Reaction Predictor: draw with Move, valence checks, S & P on the palette, tap an atom to change element, and start carbon chains with the Bond tool
• 14 quick-start structures and catalog templates tuned for accurate structure matching
• Structural formulas and diagrams for your reactant and product, including multisubstituted aromatics
• Mechanism cards show correct major/minor names and catalog yields; minor products include structures when available
• Predict requires a heavy atom (not lone H) with clearer guidance when a custom product diagram isn't available
• Bug fixes and stability improvements
