A) \[P\] and \[{{H}_{2}}S{{O}_{4}}\]
B) \[P\] and \[NaOH\]
C) \[P\] and \[{{H}_{2}}S\]
D) \[P\] and \[HN{{O}_{3}}\]
Correct Answer: B
Solution :
\[\underset{\text{(White)}}{\mathop{{{P}_{4}}+}}\,3NaOH+3{{H}_{2}}O\,\to \]\[\underset{\text{Phosphine}}{\mathop{P{{H}_{3}}}}\,+\underset{\text{Sod}\text{. hypophosphite}}{\mathop{3Na{{H}_{2}}P{{O}_{2}}}}\,\]
