JEE Main Chemistry Question (2026) — Solution
Options
- A. Na_2 O, K_2 O, Al_2 O_3 and As_2 O_3
- B. Al_2 O_3, As_2 O_3, CO and NO
- C. K_2 O, Cl_2 O_7, As_2 O_3 and NO
- D. Na_2 O, N_2 O, Al_2 O_3 and CO
Answer
C. K_2 O, Cl_2 O_7, As_2 O_3 and NO
Step-by-step solution
K_2O is a metallic oxide and is basic in nature. Cl_2O_7 is a non-metallic oxide with a high oxidation state and is acidic in nature. As_2O_3 is a metalloid oxide and is amphoteric in nature. NO is a neutral oxide. Thus, the set K_2O, Cl_2O_7, As_2O_3 and NO contains all kinds of oxides. Answer: K_2 O, Cl_2 O_7, As_2 O_3 and NO
