Vedclass · Answer

(B) The reaction of white phosphorus $(P_4)$ with $NaOH$ solution produces phosphine $(PH_3)$ via a disproportionation reaction.$Ca_3P_2$ reacts with water to yield $PH_3$ and $Ca(OH)_2$.$P_4O_6$ reacts with water to produce $H_3PO_3$ (phosphorous acid),not $PH_3$.Red phosphorus is chemically inert compared to white phosphorus and does not react with $NaOH$ solution under normal conditions.Therefore,the correct option is $(B)$.

Phosphine $(PH_3)$ is not obtained by which of the following reactions?
