A compound ' X ^ upon reaction with H ₂ O produced a colourless gas ' Y ' with rotten 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 '

Step-by-step solution

The given road map problem is As compound ' X ' produces a colorless gas ' Y ' with rotten fish smell, it can be Ca ₃ P ₂ (calcium phosphide). The reaction takes palce as follows : Ca ₃ P ₂+ H ₂ O Ca ( OH )₂+ PH ₃ Colorless gas with rotten fish smell. ' Y ' CuSO ₄+ Y ^ PH ₃ Cu ₃ P ₂+ H ₂ SO ₄
