\[{{C}_{2}}{{H}_{5}}Cl\xrightarrow[A{{g}_{2}}O]{Moist}A\xrightarrow[{{360}^{o}}C]{A{{l}_{2}}{{O}_{3}}}B\xrightarrow[{}]{{{S}_{2}}C{{l}_{2}}}\] In the above sequence of reactions, identify\[C.\]

A)  chloretone        

B)  chloropicrin

C)  mustard gas     

D)  lewisite gas

Correct Answer: C

Solution :

\[\underset{ethyl\,\,chloride}{\mathop{{{C}_{2}}{{H}_{5}}Cl}}\,\xrightarrow[A{{g}_{2}}O]{Moist}\underset{ethanol}{\mathop{{{C}_{2}}{{H}_{5}}OH}}\,\]                                                 \[\xrightarrow[{{360}^{o}}C]{A{{l}_{2}}{{O}_{3}}}\underset{\begin{smallmatrix}  ethene \\  \downarrow {{S}_{2}}C{{l}_{2}} \end{smallmatrix}}{\mathop{C{{H}_{2}}=C{{H}_{2}}}}\,\]
