In the Hinsberg test, which class of amine reacts with benzenesulphonyl chloride to form a precipita — Practical Organic Chemistry and Purification Chemistry Question
Question
In the Hinsberg test, which class of amine reacts with benzenesulphonyl chloride to form a precipitate that is completely SOLUBLE in aqueous $NaOH$?
Answer: C
💡 Solution & Explanation
Primary ($1^\circ$) amines form N-alkylbenzenesulphonamides. Due to the presence of a strongly acidic hydrogen on the nitrogen, they dissolve in basic $NaOH$.
