    Chloroethane reacts with Y to form \[NaCl\] and Z. One mole of Z reacts with two moles of HI to form water and iodoethane. Which of the following is Y?

    A) \[C{{H}_{3}}CHO\]            

    B) \[{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}\]

    C)   \[{{C}_{2}}{{H}_{5}}ONa\]         

    D)   \[C{{H}_{3}}COOH\]   

    Correct Answer: C

    Solution :

    \[C{{H}_{3}}-C{{H}_{2}}Cl+\underset{(Y)}{\mathop{{{C}_{2}}{{H}_{5}}ONa}}\,\to \underset{(Z)}{\mathop{{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}+}}\,\] \[NaCl\xrightarrow{2HI}C{{H}_{3}}-C{{H}_{2}}-I+{{H}_{2}}O\] Hence, the correct option is (a).
