The higher boiling points of alcohols as compared to isomeric ethers are due to the existence of .......... between their molecules.

Explanation

To solve the question, we need to fill in the blank with the appropriate word that explains why alcohols have higher boiling points compared to isomeric ethers.

### Step-by-Step Solution:

1. **Understanding the Context**: The question compares the boiling points of alcohols and ethers. We need to identify the reason for the difference in boiling points.

2. **Analyzing Alcohols and Ethers**:
- Alcohols contain an -OH (hydroxyl) group, which can form hydrogen bonds.
