JEE Mains · Chemistry · STD 12 - 9. Amines
Given below are two statements :
Statement I : The dipole moment of R-CN is greater than R-NC and R-NC can undergo hydrolysis under acidic medium to produce
Statement II : R-CN hydrolyses under acidic medium to produce a compound which on treatment with \(SOCl_{2}\) followed by the addition of \(NH_{3}\) gives another compound(x). This compound (x) on treatment with NaOCl/NaOH gives a product, that on treatment with \(CHCl_{3}/KOH/\Delta\) produces R-NC.
In the light of the above statements, choose the correct answer from the options given below :
- A Both Statement I and Statement II are false
- B Both Statement I and Statement II are true
- C Statement I is true but Statement II is false
- D Statement I is false but Statement II is true
Answer & Solution
Correct Answer
(D) Statement I is false but Statement II is true
Step-by-step Solution
Detailed explanation
Statement I: False \(R - NC \xrightarrow{ H _3 O ^{+}} R - NH _2+ HCOOH\) Statement II: True \(R - CN \xrightarrow{ H _3 O ^{+}} RCOOH \xrightarrow{ SOCl _2} RCOCl\) \(\xrightarrow{ NH _3} RCONH _2 \xrightarrow{ NaOCl / OH ^{-}} RNH _2\) \(\xrightarrow{ CHCl _3+ KOH } R - NC\)
