Primary amine is not formed in the reaction of
I. hydrolysis of RCN
II. reduction of RCH = NOH
III. hydrolysis of RNC
IV. hydrolysis of `R CONH_2`
The correct answer is

Options

A. I, II and IV
B. I and IV
C. II and III
D. I, II and III

Answer

B

Explanation

In I and IV, amine is not formed.
I. Hydrolysis of `RCN, RNC rarr RCOOH +NH_(3)`
II. Reduction of RCH = NOH
`RCH = NOH rarr RCH_(2)NH_(2)+H_(2)O`
III. Hydrolysis of RNC
`RNC + 2H_(2)O overset (Delta) rarr RNH_(2)+HCOOH`
IV. Hydrolysis of `RCONH_(2)`
`RCONH_(2) rarr RCOOH + NH_(3)`
