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 arrayc O ∥ R-C-OH. array Statement II : R-CN hydrolyses under acidic medium to produce a compound which on treatment with SOCl₂ , followed by the addition of NH₃ gives another compound(x). This compound (x) on treatment with NaOCl/NaOH gives a product, that on treatment with CHCl₃/KOH/Δ produces R-NC In the light of the above statements, choose the correct answer from the options given below :
