Text Solution

AI Generated Solution

The correct Answer is:
To determine which of the given species contains an O-O bond (peroxide linkage), we will analyze the structures of each compound step by step. ### Step 1: Analyze the first compound - Dichromate ion (Cr₂O₇²⁻) 1. The structure of dichromate ion can be represented as: - Cr = O (double bond) - O - Cr = O (double bond) - O - O⁻ (with a negative charge) 2. In this structure, there are no O-O bonds present. All oxygen atoms are either double-bonded to chromium or are single-bonded with a negative charge.
