    \[{{C}_{2}}{{H}_{5}}OH+X\to {{C}_{2}}{{H}_{5}}-O-{{C}_{2}}{{H}_{5}}\], X is:

    A)  with \[Na\] at \[413K\]

    B)                         with cone. \[{{H}_{2}}S{{O}_{4}}\] at \[413K\]

    C)                         with cone. \[HCl\] at \[413K\]

    D)                         with \[B{{r}_{2}}\]at \[413K\]

    Correct Answer: B

    Solution :

    \[\underset{\begin{smallmatrix}  Ethyl\,alcohol \\  in\,excess \end{smallmatrix}}{\mathop{2{{C}_{2}}{{H}_{5}}OH}}\,\xrightarrow[{{140}^{o}}C\,\,or\,\,413K]{conc.\,{{H}_{2}}S{{O}_{4}}}\] \[\underset{Di\,\,ethyl\,\,ether}{\mathop{{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}+{{H}_{2}}O}}\,\]
