Draw formulas for the first five members of each homologous series beginning with the following compounds :
`H-COOH`

Explanation

To solve the problem of drawing formulas for the first five members of the homologous series starting with methanoic acid (H-COOH), we will follow these steps:

### Step 1: Identify the Compound
The given compound is methanoic acid, which is a carboxylic acid. Its molecular formula is HCOOH.

### Step 2: Determine the General Formula
The general formula for carboxylic acids is \( C_nH_{2n}O_2 \), where \( n \) is the number of carbon atoms.
