Questions Related to alcohols, phenols and ethers

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

chemistry hydroxy compounds and ethers physical properties of ethers ethers alcohols, phenols and ethers

  1. dipolar character of ethers

  2. alcohols having resonance structures

  3. intermolecular hydrogen bonding in ethers

  4. intermolecular hydrogen bonding in alcohols

Show answer
Correct Option: D
Explanation:

An ether is more volatile than an alcohol having same molecular formula because intermolecular hydrogen bonding in alcohols. 


The $-OH$ group of alcohol can form intermolecular hydrogen bonds whereas $-O$ group of ethers cannot form hydrogen bonds. 

Hydrogen bond formation is possible when $H$ atom is attached to electronegative $N$, $O$ or $F$ atom. Intermolecular hydrogen bonds leads to molecular association. 

Hence correct answer is option D.

Ether form peroxide in contact with air and light and it may cause explosion, since the boiling point of peroxide is:
