Explanation

To write the condensed formula and bond line formula for the given compounds, we will follow a systematic approach for each part of the question.

### (a) For the compound `CH₃-CH(CH₃)-CH₂-CH₂-OH`:

1. **Condensed Formula**:
- Identify the main carbon chain and the branches.
- The main chain consists of 5 carbon atoms with a hydroxyl (OH) group at the end.
- The condensed formula can be written as:
