    Which one of the following compounds does not give \[{{C}_{2}}{{H}_{5}}Cl\]by the reaction of \[{{C}_{2}}{{H}_{5}}OH\]?

    A)  \[C{{l}_{2}}\]                                    

    B)                         \[PC{{l}_{5}}\]

    C)                         \[SOC{{l}_{2}}\]                              

    D)                         \[ZnC{{l}_{2}}+HCl\]

    Correct Answer: A

    Solution :

    \[{{C}_{2}}{{H}_{5}}OH+SOC{{l}_{2}}\to {{C}_{2}}{{H}_{5}}Cl+S{{O}_{2}}+HCl\] \[{{C}_{2}}{{H}_{5}}OH+PC{{l}_{5}}\to {{C}_{2}}{{H}_{5}}Cl+POC{{l}_{3}}+HCl\] \[{{C}_{2}}{{H}_{5}}OH+HCl\xrightarrow{ZnC{{l}_{2}}}{{C}_{2}}{{H}_{5}}Cl+{{H}_{2}}O\]
