Why do alcohols possess higher boiling points as compared to those of corresponding alkanes ?

Explanation

### Step-by-Step Solution:

1. **Understanding the Structures**:
- Alcohols have the general formula R-OH, where R is an alkyl group (like CH3 for methanol).
- Alkanes, on the other hand, have the general formula CnH2n+2 (like CH3-CH3 for ethane).

2. **Identifying Intermolecular Forces**:
- In alcohols, the presence of the hydroxyl group (-OH) allows for the formation of hydrogen bonds.
