Question

N₂ is passed through overheated CaC₂. Which of the following statements are correct for the product formed? 

I. State of hybridisation of C is sp. 

II. Urea is an intermediate formed during hydrolysis of the above product. 

III. Anion present in the product is not a pseudohalide ion. 

IV. Hydrolysis of the product gives rise to NH₃ gas slowly. 

(a) I, II and III 

(b) III and IV 

(c) I, II and IV 

(d) None of these.

Answer 1
