Assertion is wrong statement but reason is correct statement.
उत्तर
Both assertion and reason are correct statements and reason is correct explanation of assertion.
Explanation:
\[\begin{array}{cc}
\phantom{..........................}\ce{Na+}\\
\ce{C2H5 - N - SO2C6H5 + NaOH -> C2H5 -\underset{Souble salt}{N - SO2}C6H5 + H2O}\\
|\phantom{..............................................}\\
\ce{\underset{Ethylbezene sulphonamide}{H}\phantom{.............................................}}
\end{array}\]
Ethylbenzene sulphonamide is soluble in alkali because it has acidic hydrogen.
