An ether is more volatile than alcohol having the same molecular formula. This is due to:

Options

A. alcohol having resonance structures
B. intermolecular hydrogen bonding in etheres
C. intermolecular hydrogen bonding in alcohols
D. dipolar character of ethers

Explanation

To understand why an ether is more volatile than an alcohol with the same molecular formula, we can break down the explanation into clear steps:

### Step-by-Step Solution:

1. **Identify the Compounds**:
- We are comparing ethers and alcohols that have the same molecular formula. For example, consider ethanol (an alcohol) and dimethyl ether (an ether), both of which have the molecular formula C2H6O.

2. **Understand Volatility**:
- Volatility refers to how readily a substance vaporizes. A substance that is more volatile will have a lower boiling point and will evaporate more easily.

3. **Examine Intermolecular Forces**:
- The primary reason for the difference in volatility between ethers and alcohols lies in the types of intermolecular forces present in each compound.

4. **Intermolecular Hydrogen Bonding in Alcohols**:
- Alcohols contain a hydroxyl (-OH) group. The hydrogen atom of the hydroxyl group can form hydrogen bonds with the oxygen atom of another alcohol molecule. This results in strong intermolecular hydrogen bonding.

5. **Lack of Hydrogen Bonding in Ethers**:
- Ethers, on the other hand, have an ether functional group (R-O-R) where there is no hydrogen atom directly bonded to the oxygen. Therefore, ethers do not engage in hydrogen bonding like alcohols do.

6. **Effect on Boiling Point and Volatility**:
- The presence of strong hydrogen bonds in alcohols leads to higher boiling points and lower volatility compared to ethers. Since ethers lack these strong intermolecular forces, they have lower boiling points and are more volatile.

7. **Conclusion**:
- Thus, the statement that "an ether is more volatile than an alcohol having the same molecular formula" is primarily due to the absence of intermolecular hydrogen bonding in ethers, which results in lower boiling points and higher volatility.

### Final Answer:
The reason an ether is more volatile than an alcohol with the same molecular formula is due to the **intermolecular hydrogen bonding in alcohols**, which is absent in ethers.
