Which of the following is not correctly matched?
- a)Acidic oxides - P2O5, NO2, Cl2O7
- b)Basic oxides - Na2O, CaO, MgO
- c)Neutral oxides - CO2, CO, BeO
- d)Amphoteric oxides - ZnO, SnO, Al2O3
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
Which of the following is not correctly matched?a)Acidic oxides -P2O5,...
Neutral oxide- oxides which do not react with acid or base are neutral. But here CO2 is an acidic oxide and BeO dissolves in strongly acidic or basic solutions. Thus BeO is an amphoteric oxide.

Understanding Acidic, Basic, Neutral, and Amphoteric Oxides
Oxides can be classified based on their acidic or basic properties. Let's break down the classifications provided in the options.
Acidic Oxides
- Acidic oxides are typically formed from non-metals and tend to react with bases to form salts and water.
- Examples include P2O5 (phosphorus pentoxide), NO2 (nitrogen dioxide), and Cl2O7 (dichlorine heptoxide).
- These are correctly matched in option (a).
Basic Oxides
- Basic oxides are generally formed from metals and react with acids to produce salts and water.
- Common examples include Na2O (sodium oxide), CaO (calcium oxide), and MgO (magnesium oxide).
- These are correctly matched in option (b).
Neutral Oxides
- Neutral oxides do not exhibit acidic or basic properties.
- The examples in option (c) include CO2 (carbon dioxide), CO (carbon monoxide), and BeO (beryllium oxide).
- Here, CO and BeO can be considered neutral, but CO2 is an acidic oxide. Therefore, this option is incorrectly matched.
Amphoteric Oxides
- Amphoteric oxides can react with both acids and bases, displaying characteristics of both.
- Examples include ZnO (zinc oxide), SnO (tin oxide), and Al2O3 (aluminum oxide), which are correctly matched in option (d).
Conclusion
The correct answer is option 'C' because it inaccurately categorizes CO2 as a neutral oxide when it is actually an acidic oxide. Understanding these classifications is crucial for chemistry concepts, particularly in the context of reactions and compounds.
