Question

Which of the following cannot form hydrogen bonding?
A) Phenol  
B) Diethyl ether 
C) Aniline 

• A. A
• B. B
• C. C
• D. None of the above

Hint:

In hydrogen bonding, the key feature is the presence of a hydrogen atom attached to a highly electronegative element such as oxygen, nitrogen, or fluorine.

Answer 1

The Correct Option is B

Hydrogen bonding occurs when a hydrogen atom is directly bonded to a highly electronegative atom such as nitrogen (N), oxygen (O), or fluorine (F). 
Let's analyze the options: 
- Phenol: The hydroxyl group (-OH) contains hydrogen bonded to oxygen, which can form hydrogen bonds. 
- Diethyl ether: The oxygen atom in diethyl ether is bonded to carbon atoms but does not have a hydrogen atom directly bonded to it, so it cannot form hydrogen bonds. 
- Aniline: The amino group (-NH2) contains hydrogen bonded to nitrogen, allowing for hydrogen bonding. 
Thus, the correct answer is \( B \).
