Out of o-nitrophenol and o-cresol which is more acidic ?

Explanation

To determine which compound is more acidic between ortho-nitrophenol and ortho-cresol, we can follow these steps:

### Step 1: Understand the Structures
- **Ortho-nitrophenol** has a nitro group (-NO2) attached to the benzene ring at the ortho position relative to the hydroxyl group (-OH).
- **Ortho-cresol** has a methyl group (-CH3) attached to the benzene ring at the ortho position relative to the hydroxyl group.

### Step 2: Identify the Functional Groups
- Both compounds contain a hydroxyl group (-OH), which is responsible for their acidic nature. The acidity of these compounds will depend on the ability of the -OH group to release a proton (H+).
