Given below are two statements : In the light of the above statements, choose the correct answer from the options given below :
- Statement I is false but Statement II is true
- Both Statement I and Statement II are true
- Both Statement I and Statement II are false
- Statement I is true but Statement II is false
Answer
(3) Both Statement I and Statement II are false
Solution
p-Toluenesulfonyl chloride (TsCl, Ts = SO2C6H4CH3) reacts only with amines that have an N–H (1° and 2°).
C6H5NH2 + TsCl C6H5NH-Ts: acidic N–H left, so it dissolves in NaOH.
(C6H5)2NH + TsCl (C6H5)2N-Ts: no N–H left, so it is insoluble in NaOH.
(C6H5)3N has no N–H and does not react, so Statement I is false; since the product of the 2° amine is insoluble in NaOH, Statement II is false too.
Answer: (3)
