    An organic compound of molecular formula \[{{C}_{4}}{{H}_{10}}O\] does not react with sodium. With excess of \[HI,\] it gives only one type of alkyl halide. The compound is       [SCRA 2001]

    A)                 Ethoxyethane  

    B)                 2-Methoxypropane

    C)                 1-Methoxypropane       

    D)                 1-Butanol

    Correct Answer: A

    Solution :

               Since a single alkyl halide is formed on treatment with HI, it must be a symmetrical ether i.e., ethoxyethane.                 \[{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}+2HI\to 2{{C}_{2}}{{H}_{5}}I+{{H}_{2}}O\]
