Winter is coming… a blizzard of reactions is heading your way! Make learning organic chemistry easier with these customizable flashcards. Organic Reaction Cards will help you learn the reactions commonly encountered in college organic chemistry courses. In just seconds, you can set up a deck of flash cards for the reaction topics of your choice. You can configure the flash cards to hide any reaction component (reactant, reagent or product) which is then revealed upon “flipping” the card. You can even hide the reaction name separately to help you learn named reactions. Over 40 reactions covering: • Electrophilic additions of alkenes • Reactions of dienes • Electrophilic aromatic substitutions • Reactions of substituted benzenes Other Features Include: • Useful notes for each reaction regarding stereoselectivity, regioselectivity and reaction limitations • Hide any reaction component (reactant, reagent or product), great for learning to think synthetically • Delete reactions in a deck that are not covered in your class and you don’t need to learn • Created by an award winning professor of chemistry Additional cards can be purchased that cover over 150 common organic reactions!
