Given below are the oxides:
\(\mathrm{Na_2O,\ As_2O_3,\ N_2O,\ NO}\) and \(\mathrm{Cl_2O_7}\)
Number of amphoteric oxides is :
\(\mathrm{Na_2O,\ As_2O_3,\ N_2O,\ NO}\) and \(\mathrm{Cl_2O_7}\)
Number of amphoteric oxides is :
Show Hint
- 0
- 1
- 2
- 3
The Correct Option is B
Solution and Explanation
\(\mathrm{As_2O_3}\): amphoteric (dissolves in both acids and alkalis).
\(\mathrm{N_2O}\): neutral oxide.
\(\mathrm{NO}\): neutral oxide.
\(\mathrm{Cl_2O_7}\): acidic oxide (anhydride of \(\mathrm{HClO_4}\)).
Only \(\mathrm{As_2O_3}\) is amphoteric, so the number is 1.
Answer: (2) 1

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
