`C_(6)H_(5)OH` is weaker/stronger acid than `C_(6)H_(11)OH`.

Explanation

To determine whether \( C_6H_5OH \) (phenol) is a stronger or weaker acid than \( C_6H_{11}OH \) (cyclohexanol), we will analyze the stability of the conjugate bases formed when these compounds donate a proton (H⁺).

### Step 1: Identify the structures of the compounds
- **Phenol**: The structure of phenol is \( C_6H_5OH \), which consists of a benzene ring (C₆H₅) with a hydroxyl group (OH) attached.
- **Cyclohexanol**: The structure of cyclohexanol is \( C_6H_{11}OH \), which consists of a cyclohexane ring with a hydroxyl group (OH) attached.

### Step 2: Understand the concept of acidity
Acidity is defined by the ability of a compound to donate a proton (H⁺). The strength of an acid is determined by the stability of its conjugate base after the proton is lost.
