Statement (I) : All the following compounds react with p-toluenesulfonyl chloride.
Statement (II) : Their products in the above reaction are soluble in aqueous NaOH .
In the light of the above statements, choose the correct answer from the options given below.
- (A)Both Statement I and Statement II is false✓ Correct
- (B)Statement I is true but Statement II is false
- (C)Statement I is false but Statement II is true
- (D)Both Statement I and Statement II is true
Answer: (A)
Solution
In the Hinsberg test with a sulfonyl chloride (here p-toluenesulfonyl chloride), only primary and secondary amines react to give sulfonamides — a tertiary amine has no N–H left to substitute and does not react at all. Of the three named amines, aniline (1°) and diphenylamine (2°) react but triphenylamine (3°) does not, so Statement I ('all react') is false. Of the products that do form, only the primary amine's sulfonamide keeps an acidic N–H and dissolves in aqueous NaOH; the secondary amine's product does not, so Statement II ('their products are soluble') is also false.
Both statements are false.
Both statements are false.
