N₂ is passed through overheated CaC₂. Which of the following options is correct for the product formed? (I) State of hybridization 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 pseudo halide 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✓ Correct
D.None of the above
Explanation
o 1100 C 2 2 2 Calcium cyanamide CaC N CaCN C → 2 2 Ca [N C N] linear shape (sp-hybridised C-atom) On hydrolysis, calcium cyanamide gets converted into urea which then decomposes into ammonia. 2 2 CN is pseudohalide ion.
