Organic Chemistry Naming Tutor

Learn organic chemistry nomenclature as a process—not a guessing game. Organic Chemistry Nomenclature guides you from structures to correct IUPAC names and back again from names to structures. The redesigned Study Hub organizes each topic into guided learning, worked examples, practice, and mastery-focused activities so you can see how a name is built, why each decision matters, and whether you can apply the rules independently. WHAT YOU’LL LEARN • Select the correct parent chain or ring • Identify functional groups and determine the principal group • Number structures correctly • Name and alphabetize substituents • Assemble complete IUPAC names • Interpret a name and construct the matching structure • Apply R/S, E/Z, and cis/trans stereochemistry • Handle cyclic, bicyclic, aromatic, and multifunctional compounds PRACTICE BOTH DIRECTIONS Naming is more than recognizing a structure. The tutor deliberately mixes structure-to-name and name-to-structure problems to build deeper understanding and recall. TRACK MASTERY Topic-level progress and mastery indicators make it easy to see where you are strong and what still needs work. EXPLORE THE FULL LIBRARY When you want more practice, browse the complete 1,824-card library by topic and functional group, including foundational and advanced examples. Built for students taking organic chemistry, reviewing nomenclature before an exam, or strengthening the naming skills needed for reactions, mechanisms, spectroscopy, and synthesis. IUPAC note: written compound-name answers follow English Preferred IUPAC Name (PIN) conventions, while explanations and learning guidance are localized to your selected language where supported.
