Question

Options

a
$\mathrm{NO}$ and $\mathrm{N_2O}$
✓
b
$\mathrm{N_2O}$ and $\mathrm{N_2O_3}$
c
$\mathrm{N_2O}$ and $\mathrm{NO_2}$
d
$\mathrm{NO}$ and $\mathrm{NO_2}$

Correct Answera

$\mathrm{NO}$ and $\mathrm{N_2O}$

Detailed Solution

Strategy: Identify the nature (acidic/basic/neutral) of nitrogen oxides.

Step 1: Nature of Oxides Nitrogen forms several oxides:

$\ce{N2O}$ (Nitrous oxide): Neutral
$\ce{NO}$ (Nitric oxide): Neutral
$\ce{N2O3, NO2, N2O4, N2O5}$ : All are acidic.

Step 2: Conclusion The only pair consisting of two neutral oxides is $\ce{NO}$ and $\ce{N2O}$ .

$\boxed{\text{Answer: (Option) [a] $\ce{NO}$ and $\ce{N2O}$}}$
