JEE MainChemistryp Block Elements (Group 15, 16, 17 & 18)
The correct sequence of the acid-base nature of the oxides NO , BaO , Sb ₂ O ₃ , and P ₄ O ₁₀ is respectively:
Options
- AAcidic, Basic, Amphoteric, Acidic
- BNeutral, Amphoteric, Basic, Acidic
- CNeutral, Basic, Amphoteric, Acidic
- DNeutral, Basic, Basic, Acidic
Correct answer
C. Neutral, Basic, Amphoteric, Acidic
Step-by-step solution
NO is a non-metal oxide which is neutral in nature. BaO is an alkaline earth metal oxide, which is basic in nature. Sb ₂ O ₃ is an oxide of a metalloid (antimony) and is amphoteric in nature. P ₄ O ₁₀ is an oxide of a non-metal (phosphorus) in a high oxidation state, making it strongly acidic. Thus, the correct sequence is Neutral, Basic, Amphoteric, Acidic. Answer: Neutral, Basic, Amphoteric, Acidic
