Question

Which of the following compounds will dissolve in an alkali solution after it has undergone reaction with Hinsberg reagent?

• A. ${\left(C_6{H}_5\right)}_{2}NH$
• B. ${\left({CH}_3\right)}_{3}N$
• C. ${CH}_3{NH}_2$
• D. $C_6{H}_5{NHC}_6{H}_5$

Answer 1

Answer: (C)

${CH}_3{NH}_2$

Primary and secondary amines react with Hinsberg reagent. Further, only primary amines then react with alkali because of presence of one acidic hydrogen on the nitrogen atom.
So, C is the correct answer because it is a primary amine
