MCQ
A tetra-atomic molecule $(A)$ on reaction with nitrogen $(I)$ oxide, produces two substances $(B)$ and $(C).$ $(B)$ is a dehydrating agent in its monomeric form while substance $(C)$ is a diatomic gas which shows almost inert behaviour. The substances $(A)$ and $(B)$ and $(C)$ respectively will be
  • ✓
    $P_4, P_4O_{10}, N_2$
  • B
    $P_4, N_2O_5, N_2$
  • C
    $P_4, P_2O_3, Ar$
  • D
    $P_4, P_2O_3, H_2$
✓

Answer

Correct option: A.
$P_4, P_4O_{10}, N_2$
a
$\mathrm{P}_{4}+10 \mathrm{N}_{2} \mathrm{O} \rightarrow \mathrm{P}_{4} \mathrm{O}_{10}+\mathrm{N}_{2}$

So A is $\mathrm{P}_{4}$ which is a tetra-atomic molecule.

$\mathrm{B}$ is $\mathrm{P}_{4} \mathrm{O}_{10}$ which is dehydrating agent.

C is $\mathrm{N}_{2}$ is diatomic gas which shows almost inert character.
