Draw formulas for the first five members of each homologous series beginning with the following compounds :
`CH_3 COCH_3`

Explanation

To solve the problem of drawing formulas for the first five members of the homologous series starting with the compound propanone (CH₃COCH₃), we will follow these steps:

### Step 1: Identify the Given Compound
The given compound is propanone, which has the molecular formula CH₃COCH₃. This compound belongs to the ketone functional group.

### Step 2: Determine the General Formula for Ketones
The general formula for ketones is CₙH₂ₙO, where n is the number of carbon atoms in the chain. For propanone (n=3), the general formula is satisfied.
