ChemInteractive is a free online resource for students of organic chemistry created by Dr. Mike Casey (formerly of UCD School of Chemistry).
ChemInteractive provides learners with a large selection of problems on organic structure, nomenclature and reaction mechanisms so that they can test their knowledge, and hone their skills, in those areas. It provides extensive help, and detailed feedback on user's solutions, to guide them and help them learn how to solve problems in core aspects of organic chemistry.
