    From previous year papers of JEE Main & CBSE 12th Chemistry board exam we have sorted out important name reactions. If you want to learn about these name reactions then please visit the link given below

    Video: Name Reactions Asked in CBSE & IIT JEE Exams: Last 5 years Analysis

    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 year papers of JEE Main and CBSE 12th Chemistry board exams. Every year 2 to 3 name reactions are frequently asked in CBSE board exam and competitive exam like (JEE Main, JEE Advance, NEET etc).

    In this article, we will learn how to study name reactions in Organic Chemistry from examination point of view (board exam & 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 and CBSE Class 12 Chemistry board exam.

    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?


    Important Name Reactions asked in JEE Main and CBSE Board exams

    Due to the presence of concentrated alkali, carboxylic acid donates proton and form carboxylic acid salt.

    Besides these questions, it is important that student must also remember mechanism of all the name reactions.
