    A)                 \[C{{H}_{3}}O{{C}_{2}}{{H}_{5}}\]

    B)                 \[C{{H}_{3}}OC{{H}_{3}}\] and \[{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}\]

    C)                 \[C{{H}_{3}}O{{C}_{2}}{{H}_{5}}\] and \[C{{H}_{3}}OC{{H}_{3}}\]

    D)                 \[C{{H}_{3}}O{{C}_{2}}{{H}_{5}},\] \[C{{H}_{3}}OC{{H}_{3}}\] and \[{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}\]

    Correct Answer: D

    Solution :

               \[C{{H}_{3}}OH+C{{H}_{3}}OH\xrightarrow{{{H}_{2}}S{{O}_{4}}(Conc)}C{{H}_{3}}OC{{H}_{3}}\]                    \[C{{H}_{3}}OH+{{C}_{2}}{{H}_{5}}OH\xrightarrow{{{H}_{2}}S{{O}_{4}}(Conc)}C{{H}_{3}}O{{C}_{2}}{{H}_{5}}\]                 \[{{C}_{2}}{{H}_{5}}OH+{{C}_{2}}{{H}_{5}}OH\xrightarrow{{{H}_{2}}S{{O}_{4}}(Conc)}{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}\]
