Organic Chemistry Reasoning Guide This skill teaches how to think through organic chemistry problems, not what to memorize. --- 1. Predicting Reaction Products — A Reasoning Process Do NOT pattern-match to a named reaction. Instead, reason from first principles: Step 1 — Find the most reactive sites Look at each molecule and ask: where is the electron density? - Electron-rich sites (nucleophiles): lone pairs on N, O, S; pi bonds (C=C, aromatics); carbanions; enolates - Electron-poor sites (electrophiles): carbons bonded to electronegative atoms (C=O, C-X); carbocations; atoms with empty orbit…
