A) \[R-\underset{H\,\,\,}{\overset{H\,\,}{\mathop{\underset{|\,\,\,\,}{\overset{|\,\,\,\,}{\mathop{{{N}^{+}}}}}\,}}}\,-S{{O}_{2}}{{C}_{6}}{{H}_{5}}O{{H}^{-}}\]
B) \[R-{{N}^{-}}S{{O}_{2}}{{C}_{6}}{{H}_{5}}{{K}^{+}}\]
C) \[R-NHS{{O}_{2}}{{C}_{6}}{{H}_{5}}\]
D) \[{{C}_{6}}{{H}_{5}}S{{O}_{2}}N{{H}_{2}}\]
Correct Answer: C
Solution :
\[{{C}_{6}}{{H}_{5}}S{{O}_{2}}Cl+RN{{H}_{2}}\to RNHS{{O}_{2}}{{C}_{6}}{{H}_{5}}\xrightarrow{KOH}\]\[\underset{\text{soluble in }KOH}{\mathop{RNKS{{O}_{2}}{{C}_{6}}{{H}_{5}}}}\,\]
