Which out of the following is : ( a) the weakest acid (b) the strongest acid ?
(i) `C_(2)H_(5)OH` (ii) `CH_(3)COOH` (iii) `C_(6)H_(5)OH` (iv) `H_(2)O`

Explanation

To determine the weakest and strongest acids among the given compounds, we need to analyze their acidic strengths based on their ability to donate protons (H⁺ ions) and the stability of their conjugate bases.

### Step-by-Step Solution:

1. **Identify the Compounds:**
- (i) Ethanol, \(C_2H_5OH\)
- (ii) Acetic acid, \(CH_3COOH\)
- (iii) Phenol, \(C_6H_5OH\)
