which of the following oxides shows electrical properties like metals ?

Options

A. `SiO_(2)`
B. MgO
C. `SO_(2)(s)`
D. `CrO_(2)`

Explanation

To determine which of the following oxides shows electrical properties like metals, we need to analyze the nature of the given oxides. Here’s a step-by-step solution:

### Step 1: Identify the Oxides
The oxides mentioned in the question are:
1. Chromium oxide (CrO2)
2. Titanium oxide (TiO2)
3. Rhenium oxide (ReO2)
4. Silicon dioxide (SiO2)
5. Magnesium oxide (MgO)
6. Sulfur dioxide (SO2)

### Step 2: Classify the Oxides
We need to classify these oxides based on their electrical properties:
- **Metallic Oxides**: These oxides typically exhibit electrical conductivity similar to metals. Examples include CrO2, TiO2, and ReO2.
- **Non-metallic Oxides**: These oxides do not exhibit metallic properties and generally do not conduct electricity. Examples include SiO2, MgO, and SO2.

### Step 3: Analyze Each Oxide
- **CrO2 (Chromium Dioxide)**: This is a metallic oxide and shows electrical properties similar to metals.
- **TiO2 (Titanium Dioxide)**: While it has some conductivity, it is primarily a non-metal oxide and does not exhibit strong metallic properties.
- **ReO2 (Rhenium Dioxide)**: This is also a metallic oxide and can show some electrical conductivity.
- **SiO2 (Silicon Dioxide)**: This is a non-metallic oxide and does not conduct electricity.
- **MgO (Magnesium Oxide)**: This is a non-metallic oxide and does not conduct electricity.
- **SO2 (Sulfur Dioxide)**: This is a non-metallic oxide and does not conduct electricity.

### Step 4: Conclusion
From the analysis, the oxides that show electrical properties like metals are:
- Chromium Dioxide (CrO2)
- Rhenium Dioxide (ReO2)

However, since the question asks for one specific oxide that shows electrical properties like metals, the most commonly recognized one is **Chromium Dioxide (CrO2)**.

### Final Answer
**Chromium Dioxide (CrO2)** is the oxide that shows electrical properties like metals.
