    Poisonous gas 'Lewissite' is obtained by the reaction of [MP PMT 2003]

    A) \[CH\equiv CH\] and \[AsC{{l}_{3}}\]

    B) \[C{{H}_{2}}=C{{H}_{2}}\] and \[AsC{{l}_{3}}\]

    C) \[CH\equiv CH\] and \[{{S}_{2}}C{{l}_{2}}\]

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

    Correct Answer: A

    Solution :

      \[HC\equiv CH+\,AsC{{l}_{3}}\xrightarrow{{}}\underset{(\text{Lewsite})}{\mathop{\underset{\text{2-chlorovinyl dichloroarsine}}{\mathop{ClHC=CH\,AsC{{l}_{2}}}}\,}}\,\]
