The correct Answer is:
To analyze the statements provided in the question, we will break down the information regarding the separation of amines using Hinsberg reagent and their reactivity with benzene sulfonyl chloride. ### Step-by-Step Solution: 1. **Understanding the Hinsberg Test**: - The Hinsberg test is a method used to differentiate between primary, secondary, and tertiary amines. - In this test, an amine reacts with benzene sulfonyl chloride (C6H5SO2Cl) to form sulfonamides. 2. **Reaction of Primary Amines**: - When a primary amine reacts with benzene sulfonyl chloride, it forms a soluble sulfonamide. - This soluble product can be separated from the reaction mixture by dissolving it in a suitable solvent. 3. **Reaction of Secondary Amines**: - Secondary amines also react with benzene sulfonyl chloride, but they typically form a sulfonamide that is less soluble than that from primary amines. - In many cases, this leads to the formation of a precipitate, which can be separated from the solution. 4. **Reaction of Tertiary Amines**: - Tertiary amines do not react with benzene sulfonyl chloride in the same way. - They do not form a soluble sulfonamide and instead lead to the formation of a precipitate as well. 5. **Conclusion on Statement 1**: - Since primary amines yield soluble products while secondary and tertiary amines yield precipitates, we can conclude that primary, secondary, and tertiary amines can indeed be separated using the Hinsberg reagent. - Thus, Statement 1 is **True**. 6. **Understanding the Rate of Reaction**: - The rate of reaction of amines with benzene sulfonyl chloride varies due to the structure of the amines. - Primary amines have two hydrogen atoms that can be replaced, while secondary amines have one hydrogen atom. Tertiary amines lack hydrogen atoms for replacement. - This difference in hydrogen availability affects the reactivity and thus the rate of reaction with benzene sulfonyl chloride. 7. **Conclusion on Statement 2**: - Since primary, secondary, and tertiary amines react at different rates due to their structural differences, Statement 2 is also **True**. ### Final Conclusion: Both statements are true: - **Statement 1**: True (Primary, secondary, and tertiary amines can be separated by Hinsberg reagent). - **Statement 2**: True (These amines have different rates of reaction with benzene sulfonyl chloride).
