    A complete list of most important name reactions (Organic Chemistry) is available in the video given above. These reactions were most frequently asked in previous years' papers of JEE Main. Every year 2 to 3 name reactions are frequently asked in JEE Main and JEE Advanced.

    In this article, we will learn how to study name reactions in Organic Chemistry from examination point of view (engineering entrance exam).

    Here, we will learn what important points one should keep in mind while studying name reactions in Organic Chemistry. Here, we will also learn about the types of questions which are frequently asked in JEE Main.

    Let’s learn with the help of an example of Cannizzaro Reaction

    Reactants and products of Cannizzaro Reaction are shown below

    Let’s understand what types of question are asked in exams:

    • What type of Aldehyde used in Cannizzaro Reaction?

    [Hint: Aldehyde without α-Hydrogen atom]

    • What type of alkali must be used in Cannizzaro Reaction?

    [Hint: Concentrated Alkali]

    • Give an example of redox reaction from Organic Chemistry?

    [Hint: Cannizzaro Reaction

    Molecule (of the Aldehyde) Reduced to Alcohol

    Molecule Oxidized to Carboxylic Acid Salt]

    • Why is Carboxylic Acid not formed in Cannizzaro Reaction?

    [Hint:
