Give reasons for the following : (i) `C_(6)H_(5)COOH` is weaker than formic acid.

Explanation

To determine why benzoic acid (C₆H₅COOH) is a weaker acid than formic acid (HCOOH), we can analyze the structures and the effects of substituents on the acidity of these compounds. Here’s a step-by-step explanation:

### Step 1: Understand Acidity
Acidity is defined by the ability of a compound to donate a proton (H⁺). The more stable the conjugate base formed after the proton is lost, the stronger the acid.

### Step 2: Structure of Benzoic Acid and Formic Acid
- **Benzoic Acid (C₆H₅COOH)**: It has a phenyl group (C₆H₅) attached to the carboxylic acid group (COOH).
- **Formic Acid (HCOOH)**: It has a hydrogen atom attached to the carboxylic acid group.
