Question

A compound 'X’ with molecular formula \[\ce{C3H9N}\] reacts with \[\ce{C6H5SO2Cl}\] to give a solid, insoluble in alkali. Identify 'X’ and give the IUPAC name of the product. Write the reaction involved.

Answer 1

As it is given that compound X on reacting with \[\ce{C6H5SO2Cl}\] gives a solid product that is insoluble in alkali, this shows that no hydrogen is attached to N in the product.

Thus, the compound X is a secondary amine. The reaction involved is as follows:

\[\begin{array}{cc}
\ce{CH3 - N - C2H5 + C6H5SO2Cl -> CH3 - N - SO2C6H5}\\
|\phantom{...................................}|\phantom{.....}\\
\phantom{...........}\ce{\underset{(X)}{H}}\phantom{.....................}\ce{\underset{N-ethyl-N-methylbenzene sulphonamide}{C2H5}}\\
\end{array}\]
