A) \[N{{H}_{3}}\]
B) \[P{{H}_{3}}\]
C) \[{{H}_{3}}P{{O}_{4}}\]
D) \[{{H}_{3}}P{{O}_{3}}\]
Correct Answer: B
Solution :
This is the laboratory method of preparing phosphine gas. \[\underset{white}{\mathop{{{P}_{4}}}}\,+3NaOH+3{{H}_{2}}O\] \[P{{H}_{3}}+3Na{{H}_{2}}P{{O}_{2}}\] In this reaction, phosphorus disproportionate into phosphine and sodium hydrogen phosphite.You need to login to perform this action.
