NEET Chemistry Alcohols, Phenols and Ethers / एल्कोहॉल, फीनॉल तथा ईथर Question Bank Self Evaluation Test - Alcohols, Phenols and Ethers

  • question_answer
    Rate of dehydration of alcohols follows the order:

    A) \[2{}^\circ >1{}^\circ >C{{H}_{3}}OH>3{}^\circ \]

    B) \[3{}^\circ >2{}^\circ >1{}^\circ >C{{H}_{3}}OH\]

    C) \[2{}^\circ >3{}^\circ >1{}^\circ >C{{H}_{3}}OH\]

    D) \[C{{H}_{3}}OH>1{}^\circ >2{}^\circ >3{}^\circ \]

    Correct Answer: B

    Solution :

    [b] The order of dehydration among three type of alcohols is\[3{}^\circ >2{}^\circ >1{}^\circ >C{{H}_{3}}OH\]. This behaviour is related to the relative stabilities of carbocations \[\left( 3{}^\circ >2{}^\circ >1{}^\circ  \right).\]
