Given below are the oxides : Na 2 O , As 2 O 3 , N 2 O , NO and Cl 2 O 7 Number of amphoteric oxides is :

Options

  1. A0
  2. B1
  3. C2
  4. D3

Correct answer

B. 1

Step-by-step solution

Metallic oxides are basic in nature, Oxides of non-metals are mostly acidic in nature and some are neutral or amphoteric. Among the given oxides Na 2 O is a metallic oxide, and it is basic in nature. Cl 2 O 7 is a non-metal oxide and it is acidic in nature. N 2 O and NO are non-metallic oxides but are neutral in nature. As 2 O 3 is an Amphoteric oxide. It reacts with both acids and bases. So, The number of amphoteric oxides is 1.
