Organic Chemistry represents a massive portion of the Advanced Level Chemistry Paper 2. Many students lose crucial marks because they do not draw reaction mechanism arrows correctly. Let us break down the core mechanisms you must know.
Core Mechanisms Required
Common Mistakes to Avoid
- **Wrong Arrow Direction**: Arrows must ALWAYS start from a lone pair of electrons or a chemical bond, and point directly to the electron-deficient atom.
- **Missing Charges**: Do not forget the positive charge on the carbocation intermediate or the negative charge on leaving groups!
