Which of the following is a true structure of `H_(2)O_(2)` in solid phase?

Options

A.
B.
C.
D.

Explanation

To determine the true structure of hydrogen peroxide (H₂O₂) in its solid phase, we can follow these steps:

### Step 1: Understand the Molecular Structure of H₂O₂
Hydrogen peroxide (H₂O₂) consists of two hydrogen atoms and two oxygen atoms. The molecular formula indicates that it has a bent structure due to the presence of lone pairs on the oxygen atoms.

**Hint:** Recall the general structure of hydrogen peroxide and the arrangement of atoms.

### Step 2: Identify the Bonding and Angles
In H₂O₂, the oxygen atoms are connected by a single bond (O-O bond), and each oxygen atom is also bonded to a hydrogen atom. The bond angle between the hydrogen, oxygen, and the other oxygen (H-O-O) is approximately 101.9 degrees.

**Hint:** Remember that the bond angles can be influenced by lone pairs and the overall geometry of the molecule.

### Step 3: Visualize the Solid Phase Structure
In the solid phase, hydrogen peroxide adopts an "open book" structure. This means that the molecule is not linear but rather has a specific arrangement that resembles an open book. The H-O-O bond angle remains around 101.9 degrees.

**Hint:** Visualize how the atoms are arranged in a way that resembles an open book, with the hydrogen atoms positioned at the ends.

### Step 4: Choose the Correct Option
Based on the description of the structure and the bond angles, we can conclude that the correct representation of the solid phase of H₂O₂ is the one that shows the open book structure with the specified bond angle.

**Hint:** Look for the option that accurately depicts the open book structure and the bond angle of 101.9 degrees.

### Conclusion
The true structure of H₂O₂ in the solid phase is characterized by an open book arrangement with a bond angle of approximately 101.9 degrees. Therefore, the correct answer is option 3.
