Which of the following has more acid strength than the other:
2,4-dinitrophenol and 2, 4, 6-Trinitrophenol

Explanation

To determine which compound has more acidic strength between 2,4-dinitrophenol and 2,4,6-trinitrophenol, we can follow these steps:

### Step 1: Understand the Structures
- **2,4-Dinitrophenol** has two nitro groups (-NO2) attached to the benzene ring at the 2nd and 4th positions.
- **2,4,6-Trinitrophenol** has three nitro groups (-NO2) attached to the benzene ring at the 2nd, 4th, and 6th positions.

### Step 2: Identify the Role of Nitro Groups
- Nitro groups are electron-withdrawing groups. They stabilize the negative charge that forms when the hydroxyl group (–OH) loses a proton (H+), making it easier for the compound to donate a proton.
