The oxidation of toluene with ............ gives benzaldehyde.

Explanation

To solve the question: "The oxidation of toluene with ............ gives benzaldehyde," we will follow these steps:

### Step 1: Identify Toluene
Toluene is an aromatic compound with the chemical formula C7H8. It consists of a benzene ring (C6H5) with a methyl group (–CH3) attached to it.

### Step 2: Understand the Oxidation Process
When toluene undergoes oxidation, the methyl group (–CH3) is oxidized to form an aldehyde group (–CHO), resulting in benzaldehyde (C6H5CHO).
