Given below are two statements :
Statement (I) : All the following compounds react with p-toluenesulfonyl chloride.
\(C_6 H_5 NH_2 \quad\left(C_6 H_5\right)_2 NH \quad\left(C_6 H_5\right)_3 N\)
Statement (II) : Their products in the above reaction are soluble is aqueous NaOH.
In the light of the above statements, choose the correct answer from the options given below
- A Statement I is false but Statement II is true
- B Statement I is true but Statement II is false
- C Both Statement I and Statement II are true
- D Both Statement I and Statement II are false
Answer & Solution
Correct Answer
(D) Both Statement I and Statement II are false
Step-by-step Solution
Detailed explanation
P - tolenesulfonyl chloride is Heisenberg reagent. ⇒ gives reaction with Primary and secondary amines not with tertiary. ⇒ Product of \(1^{\circ}\) Amine ⇒ Soluble in Base (NaOH) Product of \(2^{\circ}\) Amine ⇒ Soluble in acid \(( HCl )\)
