What happens when phenol is oxidized by `Na_(2)Cr_(2)O_(7)//H_(2)SO_(4)?`

Explanation

To determine what happens when phenol is oxidized by sodium dichromate (Na₂Cr₂O₇) in the presence of sulfuric acid (H₂SO₄), we can follow these steps:

### Step 1: Identify the Reactants
- The reactant in this reaction is phenol (C₆H₅OH), which is an aromatic compound with a hydroxyl group (-OH) attached to a benzene ring.
- The oxidizing agent is sodium dichromate (Na₂Cr₂O₇) in an acidic medium provided by sulfuric acid (H₂SO₄).

### Step 2: Understand the Oxidation Process
- In organic chemistry, oxidation typically involves the addition of oxygen or the removal of hydrogen.
