Question:
An organic compound "A" on treatment with benzene sulphonyl chloride gives compound $\mathrm{B}$. B is soluble in dil. $\mathrm{NaOH}$ solution. Compound $\mathrm{A}$ is:
$\mathrm{C}_{6} \mathrm{H}_{5}-\mathrm{N}-\left(\mathrm{CH}_{3}\right)_{2}$
$\mathrm{C}_{6} \mathrm{H}_{5}-\mathrm{NHCH}_{2} \mathrm{CH}_{3}$
$\mathrm{C}_{6} \mathrm{H}_{5}-\mathrm{CH}_{2} \mathrm{NHCH}_{3}$
Correct Option: , 4
Solution:
Hinsberg reagent (Benzene sulphonyl chloride) gives reaction product with $1^{\circ}$ amine and it is soluble in dil. $\mathrm{NaOH}$.
