    Common Myths About JEE Main Chemistry

    MYTH
    Organic Chemistry in JEE Main requires memorising every reaction
    FACT
    Most organic reactions follow the same mechanisms (SN1/SN2, electrophilic addition, EAS). Understanding mechanisms lets you predict products without memorising each reaction individually.
    MYTH
    Inorganic Chemistry is all about rote learning
    FACT
    While some facts must be memorised (like oxoacid structures), most inorganic questions can be answered by understanding periodic trends and basic bonding concepts.
