In learning the organic chemistry, the hurdle is how to remember all the organic reactions. The best way to remember all organic reactions is, with the help of reagents used in the organic reactions. While going through different organic reactions you will notice that same reagents are used many times, it means same reagent can have different functions, for example a very special reagent "GRIGNARD REAGENT (RMgX)" can be used as a base to react with water, alcohol, terminal alkyne etc. to give alkane R-H as well as can react with aldehydes (R-CHO) and ketones (RCOR) as a nucleophile to give alcohols, so instead of memorizing all the reactions it is better to know the functions of different reagents. We are (via this app) providing you that list of reagents that will help you in remembering all important reactions of organic chemistry. All the best and enjoy organic chemistry. The app is completely ads free.
