Answer

To determine the true structure of hydrogen peroxide (H₂O₂), we need to analyze its molecular geometry and bonding characteristics. Here’s a step-by-step solution:

### Step 1: Understand the Molecular Formula
Hydrogen peroxide has the molecular formula H₂O₂, which indicates it consists of two hydrogen atoms and two oxygen atoms.

### Step 2: Determine the Molecular Geometry
Hydrogen peroxide is known to have a non-planar structure. The arrangement of atoms in H₂O₂ is not flat; instead, it adopts an "open book" conformation. This means that the molecule has a certain degree of flexibility and is not in a single plane.

### Step 3: Analyze Bond Angles and Distances
In H₂O₂, the bond angle between the oxygen-oxygen-hydrogen (O-O-H) bonds is approximately 101.5 degrees. This angle is indicative of the non-linear arrangement of the atoms in the molecule.

### Step 4: Identify the Correct Structure
Given the characteristics of H₂O₂, we can eliminate options that suggest a planar structure. The correct structure must reflect the open book conformation and the specified bond angles and distances.

### Step 5: Conclusion
Based on the analysis, the true structure of H₂O₂ is the one that represents it as a non-planar molecule with an open book structure. Therefore, the correct option is the one that aligns with these characteristics.
