A) In the preparation of compounds of Xe, Bartlett had taken \[{{O}_{2}}P\,t{{F}_{6}}\] as a base compound because both \[{{O}_{2}}\] and Xe have almost same ionisation enthalpy.
B) Nitrogen does not show allotropy.
C) A brown ring is formed in the ring test for \[N{{O}_{3}}^{-}\] ion. It is due to the formation of \[{{[Fe{{({{H}_{2}}O)}_{5}}(NO)]}^{2+}}\]
D) On heating with concentrated NaOH solution in an inert atmosphere of \[C{{O}_{2}}\], red phosphorus gives \[P{{H}_{3}}\] gas.
Correct Answer: D
Solution :
On heating with concentrated \[NaOH\] solution in an inert atmosphere of \[C{{O}_{2}}\] white phosphorus gives gas.
