Write the formulae and names of the first three carboxylic acids.

Explanation

To solve the question about the first three carboxylic acids, we will follow these steps:

### Step 1: Understand Carboxylic Acids
Carboxylic acids are organic compounds that contain a carboxyl group (-COOH). The general formula for carboxylic acids can be represented as CnH2n+1COOH, where "n" is a non-negative integer.

### Step 2: Identify the First Three Carboxylic Acids
We will calculate the molecular formula and names of the first three carboxylic acids by substituting values for "n".
