A) White phosphorus
B) Red phosphorus
C) Both (a) and (b)
D) None of these
Correct Answer: A
Solution :
White phosphorus on heating with aqueous solution of \[KOH\]produce phosphene \[(P{{H}_{3}})\]gas. \[\underset{\begin{smallmatrix} \,\,\,\,\,\,\,\,\,White \\ \,\,\,\,\,\,\,phosphorus \end{smallmatrix}}{\mathop{{{P}_{4}}}}\,+3KOH+3{{H}_{2}}O\xrightarrow{{}}3K{{H}_{2}}P{{O}_{2}}\] \[\underset{Phosphene}{\mathop{+P{{H}_{2}}}}\,\]
