Among the compounds shown below which one revealed a linear structure ?

Options

A. `NO_2`
B. `HOCl`
C. `O_3`
D. `N_2O`

Answer

To determine which of the given compounds has a linear structure, we can follow these steps:

### Step 1: Identify the Compounds
First, we need to identify the compounds provided in the question. For the sake of this solution, let's assume the compounds are:
1. Ozone (O₃)
2. Nitrous oxide (N₂O)
3. Hydrogen chloride (HCl)
4. Nitrogen dioxide (NO₂)

### Step 2: Analyze the Structures
Next, we analyze the molecular geometry of each compound using VSEPR theory or hybridization.

#### 1. Ozone (O₃)
- Ozone has a bent structure due to the presence of a lone pair on the central oxygen atom. The bond angle is approximately 117 degrees.

#### 2. Nitrous oxide (N₂O)
- Nitrous oxide has a linear structure. It consists of two nitrogen atoms and one oxygen atom. The bond angle is 180 degrees, indicating a linear arrangement.

#### 3. Hydrogen chloride (HCl)
- Hydrogen chloride is a diatomic molecule, which is inherently linear. However, it does not fit the context of multiple atoms in the question.

#### 4. Nitrogen dioxide (NO₂)
- Nitrogen dioxide has a bent structure due to the presence of one lone pair on the nitrogen atom. The bond angle is approximately 134 degrees.

### Step 3: Conclusion
From the analysis above, the compound that reveals a linear structure is **Nitrous oxide (N₂O)**.

### Final Answer
The correct option is **N₂O**.
