Nitrogen Containing CompoundHard

Question

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 :

Options

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

Solution

Statement I : False

$$R - NC\overset{\phantom{H_{3}O^{+}\ }}{\rightarrow}R - {NH}_{2} + HCOOH $$Statement II : True

$$R - CN\overset{\phantom{H_{3}O^{+}\ }}{\rightarrow}RCOOH\overset{\phantom{{SOCl}_{2}\ }}{\rightarrow}RCOCl\overset{\phantom{{NH}_{3}\ }}{\rightarrow}{RCONH}_{2}\overset{\phantom{NaOCl/{OH}^{-}\ }}{\rightarrow}{RNH}_{2}\ \overset{\phantom{{CHCl}_{3} + KOH\ }}{\rightarrow}R - NC$$
