    Conc. \[{{H}_{2}}S{{O}_{4}}\] heated with excess of \[{{C}_{2}}{{H}_{5}}OH\] at \[{{140}^{o}}C\] to form               [MP PMT 1990; RPMT 2000; AFMC 2002]

    A)                 \[C{{H}_{3}}C{{H}_{2}}-O-C{{H}_{3}}\]

    B)                 \[C{{H}_{3}}C{{H}_{2}}-O-C{{H}_{2}}C{{H}_{3}}\]

    C)                 \[C{{H}_{3}}-O-C{{H}_{2}}-C{{H}_{2}}-C{{H}_{3}}\]

    D)                 \[C{{H}_{2}}=C{{H}_{2}}\]

    Correct Answer: B

    Solution :

               \[C{{H}_{3}}C{{H}_{2}}-OH+HO-C{{H}_{2}}-C{{H}_{3}}\underset{{{140}^{o}}C}{\mathop{\xrightarrow{\text{Conc}\text{.}\,\,{{H}_{2}}S{{O}_{4}}}}}\,\]                                                 \[\underset{\text{Diethyl}\,\,\text{ether}}{\mathop{C{{H}_{3}}C{{H}_{2}}-O-C{{H}_{2}}-C{{H}_{3}}}}\,+{{H}_{2}}O\]
