Organic Nomenclature 2026

Organic Nomenclature Practice is a fully offline study tool for students preparing for high school chemistry competitions, introductory college organic chemistry, pharmacy, and chemistry-related courses. The app is designed around common learning problems: many functional groups, confusing naming rules, and a lack of systematic practice converting between structures and names. No login or internet connection is required. All practice records, mistakes, and progress are stored locally on your device. Key features: 1. Functional group and nomenclature reference: covers common categories including alkanes, alkenes, alkynes, alcohols, aldehydes, ketones, carboxylic acids, esters, and amines. 2. Name recognition practice: choose the correct structural features from a name and train main chain, numbering, and substituent order judgment. 3. Structure naming practice: work step by step through parent chains, functional groups, substituents, and numbering. 4. Mistake review: automatically records missed questions for review by question type and functional group. 5. Study statistics: track accuracy, practice streaks, weak functional groups, and history. Useful for repeated practice, exam review, and offline self-study.
