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

A)  chloretone

B)  cloropicrin

C)   mustard gas

D)  lewisite gas

Correct Answer: C

Solution :

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