JEE Main 2024 Chemistry question
An amine (X) is prepared by ammonolysis of benzyl chloride. On adding p-toluenesulphonyl chloride to it the solution remains clear. Molar mass of the amine (X) formed is g mol⁻¹. (Given molar mass in g mol⁻¹ C : 12, H : 1, O : 16, N : 14)
Answer: 287
Solution
A clear solution with TsCl (Hinsberg test) means no reaction, so the amine is tertiary: tribenzylamine (C₆H₅CH₂)₃N, C₂₁H₂₁N = 287 g mol⁻¹.
