    Structural formula of Lewisite is

    A) \[\underset{CHAsC{{l}_{3}}}{\mathop{\underset{||}{\mathop{CHCl}}\,}}\,\]               

    B) \[\underset{CHAsCl}{\mathop{\underset{||}{\mathop{CHCl}}\,}}\,\]   

    C)        \[\underset{CHAsC{{l}_{2}}}{\mathop{\underset{||}{\mathop{CHCl}}\,}}\,\]    

    D)        \[\underset{CHAsC{{l}_{2}}}{\mathop{\underset{||}{\mathop{C{{H}_{2}}}}\,}}\,\]

    Correct Answer: C

    Solution :

    Lewisite is obtained when acetylene reacts with arsenic chloride. \[CH\equiv CH\xrightarrow{AsC{{l}_{3}}}\underset{Lewisite}{\mathop{CHCl=CHAsC{{l}_{2}}}}\,\]
