The oxide that does not act as an insulator even by a change in temperature

Options

A. `VO_(2)`
B. `TiO`
C. `VO`
D. `TiO_(2)`

Answer

To determine the oxide that does not act as an insulator even with a change in temperature, we need to analyze the electrical conductivity of different metal oxides. Here’s a step-by-step solution:

### Step 1: Identify the Types of Metal Oxides
Metal oxides can generally be classified into three categories based on their electrical conductivity:
- Insulators (do not conduct electricity)
- Semiconductors (conduct electricity under certain conditions)
- Conductors (conduct electricity well)

### Step 2: Analyze the Given Oxides
The question mentions several oxides:
1. Vanadium oxide (VO)
2. Titanium dioxide (TiO2)
3. Titanium monoxide (TiO)

### Step 3: Determine the Conductivity of Each Oxide
- **Vanadium oxide (VO)**: This oxide is known to exhibit semiconductor properties. It can conduct electricity under certain conditions, such as changes in temperature.
- **Titanium dioxide (TiO2)**: This oxide is typically an insulator and does not conduct electricity well, even with changes in temperature.
- **Titanium monoxide (TiO)**: This oxide is a conductor. It can conduct electricity and does not behave as an insulator, regardless of temperature changes.

### Step 4: Conclusion
From the analysis, we find that **Titanium monoxide (TiO)** is the oxide that does not act as an insulator, even with a change in temperature. It behaves as a conductor.

### Final Answer
The oxide that does not act as an insulator even by a change in temperature is **Titanium monoxide (TiO)**.
