Question

Complete the reaction: `HCN + 2H_2O -> ?` Also, how is oxamide prepared? What is the reaction for its preparation?

Answer 1

cyanide on hydrolysis gives carboxylic acids.

Explanation:

HCN+2H2O→ HCOOH

steps:
(1) `H-C-=N + H_"2"O → H-C(OH)=NH`
(2) `H-C(OH)=NH + H_"2"O →H-C(OH)_"2"NH2`

(3) `H-C(OH)_"2"NH2` will further give HCOOH + NH3

• OXAMIDE formation:

`(CN)_"2"+ H2O+ HCl rarr NH2-CO-CO-NH2`

(USING same process as above)
