JEE Main 2026 — 2 April, Evening Shift — Question 54

The correct set that contains all kinds (basic, acidic, amphoteric and neutral) of oxides is:

Option A:
$\mathrm{Na}_{2} \mathrm{O}, \mathrm{K}_{2} \mathrm{O}, \mathrm{Al}_{2} \mathrm{O}_{3}$ and $\mathrm{As}_{2} \mathrm{O}_{3}$
Option B:
$\mathrm{Al}_{2} \mathrm{O}_{3}, \mathrm{As}_{2} \mathrm{O}_{3}, \mathrm{CO}$ and NO
Option C:
$\mathrm{K}_{2} \mathrm{O}, \mathrm{Cl}_{2} \mathrm{O}_{7}, \mathrm{As}_{2} \mathrm{O}_{3}$ and NO
Correct
Option D:
$\mathrm{Na}_{2} \mathrm{O}, \mathrm{N}_{2} \mathrm{O}, \mathrm{Al}_{2} \mathrm{O}_{3}$ and CO

Answer: C

Step-by-step solution

Basic Oxides : $\mathrm{Na}_{2} \mathrm{O}, \mathrm{K}_{2} \mathrm{O}$ Acidic Oxides : $\mathrm{Cl}_{2} \mathrm{O}_{7}$ Neutral Oxides : $\mathrm{N}_{2} \mathrm{O}$ , NO & CO Amphoteric Oxides : $\mathrm{Al}_{2} \mathrm{O}_{3}, \mathrm{As}_{2} \mathrm{O}_{3}$
