QUESTION #65 Cyanides and Isocyanides
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 beginarrayc mathrmO \\ mathrm parallel \\ mathrmR-C-OH. endarray 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 :
