A compound ' X ' upon reaction with H 2 O produces a colorless gas 'Y' with rotton fish smell. Gas 'Y' is absorbed in a solution of CuSO 4 to give Cu 3 P 2 as one of the products. Predict the compound ' X '

Question

A compound ' X ' upon reaction with H 2 O produces a colorless gas 'Y' with rotton fish smell. Gas 'Y' is absorbed in a solution of CuSO 4 to give Cu 3 P 2 as one of the products. Predict the compound ' X ' (A) Ca3P2 (B) NH4Cl (C) As2O3 (D) Ca3(PO4)2

underset(X)Ca3P2 + H2O arrow Ca(OH)2 + underset textColourless gas (y)PH3 CuSO4 + underset(y)PH3 arrow Cu3P2 + H2SO4 hence X is Ca3P2 (Calcium phosphide)

Q. A compound ' $X$ ' upon reaction with $H_{2} O$ produces a colorless gas 'Y' with rotton fish smell. Gas 'Y' is absorbed in a solution of $C u S O_{4}$ to give $C u_{3} P_{2}$ as one of the products. Predict the compound ' $X$ '

$C a_{3} P_{2}$

$N H_{4} Cl$

$A s_{2} O_{3}$

$C a_{3} (P O_{4})_{2}$

$(X) C a_{3} P_{2} + H_{2} O \to C a (O H)_{2} + Colourless gas (y) P H_{3}$
$C u S O_{4} + (y) P H_{3} \to C u_{3} P_{2} + H_{2} S O_{4}$
hence $X$ is $C a_{3} P_{2}$ (Calcium phosphide)
