Organic Nomenclature 2026

Study basic organic chemistry offline with nomenclature rule lookup, structure recognition, focused drills, and mistake review.

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.
