Question

An oxide of carbon (X) reacts with ammonia to produce urea an important fertilizer. Which of the following combinations will not yield (X). (A) CO2-3 +HCl xrightarrowΔ (B) CaO +HC xrightarrowΔ (C) C+Excess +O2 xrightarrowΔ (D) HCO3- +HCl xrightarrowΔ

(X) is CO2 because CO2 + NH3 under pressure gives urea, reaction (b) does not produce CO2 CaO +C xrightarrowΔ CaC2 +CO

Q. An oxide of carbon (X) reacts with ammonia to produce urea an important fertilizer. Which of the following combinations will not yield (X).

$C O_{3}^{2 -} + H Cl Δ$

$C a O + H C Δ$

$C + E x cess + O_{2} Δ$

$H C O_{3}^{-} + H Cl Δ$

$(X)$ is $C O_{2}$ because $C O_{2} + N H_{3}$ under pressure gives urea, reaction (b) does not produce $C O_{2}$
$C a O + C Δ C a C_{2} + CO$
