Q 3 :

Given below are two statements:                                        [2026]

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 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:

  • Statement I is false but Statement II is true

     

  • Statement I is true but Statement II is false

     

  • Both Statement I and Statement II are true

     

  • Both Statement I and Statement II are false

     

(1)

Statement I : False

R-NC→H3O+R-NH2+HCOOH

Statement II : True

R-CN→H3O+RCOOH→SOCl2RCOCl→NH3RCONH2→NaOCl/OH-RNH2→CHCl3+KOHR-NC
