Alchemie's Mechanisms app puts electrons in your hands. Move them, push them, and learn why reactions happen, not just what they look like. Over 260 puzzles covering both semesters of organic chemistry.
One-time purchase for all puzzles, 50 free puzzles included in demo
Arrow pushing is the hardest skill in organic chemistry and most students only practice it on paper. Static diagrams and worked examples can show you what a mechanism looks like, but understanding why electrons move (and being able to predict it yourself) requires a different kind of practice.
Mechanisms gives students a place to actually push electrons, make mistakes, and build intuition through guided exploration.
Move and manipulate electrons to form and break bonds while completing real reaction mechanisms. See the resultant structure form as electrons are rearranged.
Use Mechanisms on the web or download the iOS app. No Android version currently available.
Immediate feedback tells you not just whether electron movements occur or not. Textual feedback for common mistakes helps you understand why, building mechanistic reasoning with every attempt.
Covers both semesters of organic chemistry, from introductory mechanisms through advanced carbonyl chemistry. Structured to build skills progressively as the course advances.
