Amines · Nitrile isocyanide hydrolysis and carbylamine

Given below are two statements :

Statement I : The dipole moment of $\ce{R-CN}$ is greater than $\ce{R-NC}$ and $\ce{R-NC}$ can undergo hydrolysis under acidic medium to produce

Statement II : $\ce{R-CN}$ hydrolyses under acidic medium to produce a compound which on treatment with $\ce{SOCl2}$ , followed by the addition of $\ce{NH3}$ gives another compound(x). This compound (x) on treatment with NaOCl/NaOH gives a product, that on treatment with $\ce{CHCl3}$ /KOH/ $\Delta$ produces $\ce{R-NC}$

In the light of the above statements, choose the correct answer from the options given below :

(1)Both Statement I and Statement II are false
(2)Both Statement I and Statement II are true
(3)Statement I is true but Statement II is false
(4)Statement I is false but Statement II is true
