Arranging the oxides in increasing order of basic nature:


The basic nature of an oxide depends on the ability of the oxide to accept protons (H+ ions) from water, forming hydroxide ions (OH-). The greater the ability to accept protons, the stronger the basic nature of the oxide.


Let's analyze the oxides of elements X, Y, and Z:


Oxide of element X:

The atomic number of X is 11, which corresponds to the element sodium (Na). Sodium oxide (Na2O) is formed when sodium reacts with oxygen. The chemical equation for the reaction is:

4Na + O2 → 2Na2O

Sodium oxide is a basic oxide because it reacts with water to form sodium hydroxide (NaOH), a strong base. The reaction is:

Na2O + H2O → 2NaOH


Oxide of element Y:

The atomic number of Y is 7, which corresponds to the element nitrogen (N). Nitrogen oxide (NO) is formed when nitrogen reacts with oxygen. The chemical equation for the reaction is:

N2 + O2 → 2NO

Nitrogen oxide is a neutral oxide because it does not react with water. It neither has basic nor acidic properties.


Oxide of element Z:

The atomic number of Z is 16, which corresponds to the element sulfur (S). Sulfur oxide (SO2) is formed when sulfur reacts with oxygen. The chemical equation for the reaction is:

S + O2 → SO2

Sulfur oxide is an acidic oxide because it reacts with water to form sulfurous acid (H2SO3). The reaction is:

SO2 + H2O → H2SO3


Arranging the oxides in increasing order of basic nature:


  1. Nitrogen oxide (NO)

  2. Sulfur oxide (SO2)

  3. Sodium oxide (Na2O)



Explanation:

Based on the reactivity with water, the oxides can be arranged in increasing order of basic nature. Nitrogen oxide (NO) does not react with water, so it is neutral. Sulfur oxide (SO2) reacts with water to form a weak acid, making it less basic than sodium oxide (Na2O), which reacts with water to form a strong base (sodium hydroxide).
