Oxygen stablises higher oxidation state because

Options

A. It is electronegative
B. Of its tendency to form double bond
C. of small size
D. of large size

Answer

To solve the question "Oxygen stabilizes higher oxidation state because," we need to analyze the given options and understand the properties of oxygen that contribute to its ability to stabilize higher oxidation states.

### Step-by-Step Solution:

1. **Understanding Oxidation States**:
- Oxidation state refers to the degree of oxidation of an atom in a compound. Higher oxidation states indicate that an atom has lost more electrons.

2. **Analyzing the Options**:
- **Option 1: It is electronegative**: While oxygen is indeed highly electronegative, this property alone does not directly explain its ability to stabilize higher oxidation states.
- **Option 2: Its tendency to form double bonds**: Oxygen can form double bonds with other elements, which can stabilize higher oxidation states. This is a strong contender.
- **Option 3: Small size**: The small size of oxygen allows it to form effective bonds, but it does not directly relate to stabilizing higher oxidation states.
- **Option 4: Large size**: This option is incorrect as oxygen is not large; it is one of the smaller elements.

3. **Selecting the Best Option**:
- The most relevant option is **Option 2: Its tendency to form double bonds**. This property allows oxygen to engage in multiple bonding with metals, which stabilizes the metal in higher oxidation states.

4. **Conclusion**:
- Therefore, the correct answer is that oxygen stabilizes higher oxidation states because of its tendency to form double bonds.

### Final Answer:
Oxygen stabilizes higher oxidation states because of its tendency to form double bonds (Option 2).
