Fundamental to a student's understanding of organic chemistry is the ability to interpret and use its language, including molecules' names and other key terms. A learning gap exists in that students often struggle with organic nomenclature. Although many resources describe the rules for naming molecules, there is a paucity of resources available to actively and independently practice naming and drawing molecules and receiving feedback; plus, many of these resources are of low quality. Furthermore, students often do not see the real-life applications of the molecules they are naming. Our team created www.nomenclature101.com to respond to the learning gap and the lack of quality resources and to provide a link to real-life applications. This Web site hosts a free, interactive, online, bilingual (English/French) learning tool that draws from a bank of almost 1000 questions. This online learning tool is student-driven; it allows students to tailor their learning to their needs by creating customized nomenclature quizzes and providing immediate feedback. Nomenclature101.com has three key learning objectives; after working through the quizzes and other learning supports, students can (i) identify functional groups in a given molecule, (ii) name a molecule, given its structure, and (iii) draw a molecule, given its name. The learning tool is designed for high school chemistry and introductory organic chemistry courses. Students can use the tool independently or based on specific recommendations from their instructor; additionally, instructors could generate and print quizzes to use as part of their course assessment.
