Name Reactions

What are Named Reactions?

Name reactions are those chemical reactions which are named after the scientists who discovered or developed them. This trend started in 1822 with scientist Lieben. He studied the reaction of many carbonyl compounds with iodine and alkali and postulated rules that formed the basis of the iodoform test. This is the reason, the reaction was named after Lieben and was called LIeben Haloform Reaction. Presently, hundreds of well-known organic reactions have been named after scientists. All these name reactions are very important for board examinations and competitive exams such as IIT JEE, NEET etc. 

If you are in class 12 then all name reactions are very important for to score good in the board exam and clear JEE or NEET exams. Here we are providing you a list of important named reactions in organic chemistry which will be handy for you during revision. We have linked listed named reactions with separate pages as well in which named reactions are given with detailed description, mechanisms and applications.
