Parent structures
Identify chains, rings, unsaturation, and the structural feature that controls the parent name.
Stage 2 · Organic Chemistry Suite
Focused IUPAC nomenclature practice.
Build the pattern recognition needed to move confidently between organic structures and systematic names. Practice IUPAC nomenclature with more than 1,600 structures, targeted quizzes, flashcards, and reference tools.

IUPAC nomenclature practice
Organic chemistry naming becomes faster when you repeatedly identify the parent chain, assign locants, recognize functional groups, and assemble names in a consistent order. This app gives that process a focused place to practice.
Use flashcards for quick recognition, build a custom quiz around the categories you need, and reinforce stereochemical naming alongside common functional groups.
Identify chains, rings, unsaturation, and the structural feature that controls the parent name.
Practice priority, suffixes, prefixes, locants, and substituent organization.
Reinforce naming conventions for stereochemical relationships and molecular configuration.
Move between line structures and names until the patterns become familiar.
