JEE MAIN - Chemistry (2022 - 24th June Morning Shift - No. 5)
Given below are the oxides:
Na2O, As2O3, N2O, NO and Cl2O7
Number of amphoteric oxides is :
0
1
2
3
Explanation
Oxides
$\mathrm{Na}_2 \mathrm{O} \longrightarrow$ Basic
$\mathrm{As}_2 \mathrm{O}_3 \longrightarrow$ Amphoteric
$\mathrm{N}_2 \mathrm{O} \longrightarrow$ Neutral
$\mathrm{NO} \longrightarrow$ Neutral
$\mathrm{Cl}_2 \mathrm{O}_7 \longrightarrow$ Acidic
Hence, only one amphoteric oxide is present.
