Vedclass · Answer

(A) $(i)$ Calcium phosphide reacts with water to produce phosphine: $Ca_3P_2 + 6H_2O \rightarrow 3Ca(OH)_2 + 2PH_3$.$(ii)$ White phosphorus reacts with concentrated $NaOH$ solution in an inert atmosphere to produce phosphine: $P_4 + 3NaOH + 3H_2O \rightarrow PH_3 + 3NaH_2PO_2$.$(iii)$ Red phosphorus is much less reactive than white phosphorus and does not react with alkali to give phosphine under these conditions.

Which of the following reactions give phosphine $(PH_3)$?
$(i)$ Reaction of calcium phosphide with water
$(ii)$ Heating white phosphorus with concentrated $NaOH$ solution in an inert atmosphere
$(iii)$ Heating red phosphorus with alkali
