हिन्दीA compound 'X' upon reaction with \( \mathrm{H_2O} \) produces a colourless gas 'Y' with rotten fish smell. Gas 'Y' is absorbed in a solution of \( \mathrm{CuSO_4} \) to give \( \mathrm{Cu_3P_2} \) as one of the products. Predict the compound 'X'.
Correct answer · Option 2
\( \mathrm{Ca_3P_2} \)
Explanation
\( \mathrm{Ca_3P_2} \) reacts with water to produce phosphine gas \( (\mathrm{PH_3}) \), which has a rotten fish smell and reacts with \( \mathrm{CuSO_4} \) to form \( \mathrm{Cu_3P_2} \).
