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

  • question_answer
    A compound of the formula \[{{C}_{4}}{{H}_{10}}O\] reacts with sodium and undergoes oxidation to give a carbonyl compound which does not reduce Tollen's reagent, the original compound is

    A) Diethyl ether      

    B) n-Butyl alcohol

    C) Isobutyl alcohol

    D) sec-Butyl alcohol

    Correct Answer: D

    Solution :

    [d] Since the compound \[({{C}_{4}}{{H}_{10}}O)\] react with sodium, it must be alcohol (option b, c, or d). As it is oxidised to carbonyl compound which does not reduce Tollen's reagent, the carbonyl compound should be a ketone and the \[{{C}_{4}}{{H}_{10}}O\] should be a secondary alcohol, i.e. sec-butyl alcohol; other two given alcohols are \[1{}^\circ \].
