Oxides

Neutral oxides are those oxides which do not show acidic or basic properties. They are neither acidic nor basic but may exhibit amphoteric properties.

1. Step 1: Understanding the given oxides: - : This is an amphoteric oxide because it reacts both as an acid and a base. - : This is an acidic oxide, as it reacts with water to form an acidic solution. - : This is a neutral oxide, as it does not show acidic or basic properties. - : Carbon monoxide is a neutral oxide, as it does not exhibit acidic or basic properties.

2. Step 2: Identify the neutral oxides: The neutral oxides in the options are (dinitrogen monoxide) and (carbon monoxide). Thus, the correct answer is (B) .

The most basic oxide is one that readily reacts with water to form a base. Chromium(III) oxide ( ) is the most basic oxide among the given options.
