Draw the structures for the following compounds.
(i) Ethanoic acid , (ii) Bromopentane
(iii) Butanone , (iv) Hexanal

Explanation

To draw the structures for the compounds given in the question, we will follow these steps for each compound:

### (i) Ethanoic Acid (CH3COOH)
1. **Identify the Formula**: Ethanoic acid has the molecular formula CH3COOH.
2. **Draw the Carbon Backbone**: Start with 2 carbon atoms. The first carbon (C1) will have three hydrogen atoms (H) attached to it, and the second carbon (C2) will be part of the carboxylic acid group (COOH).
3. **Add the Carboxylic Group**: The second carbon (C2) will have a double bond with oxygen (O) and a single bond with a hydroxyl group (OH).
4. **Complete the Structure**: The final structure will be:
```
