A) more polarising power
B) presence of hydrogen bonding
C) resonance stabilisation
D) acidic character
Correct Answer: B
Solution :
Key Idea: Hydrogen bonds are strong forces of attraction existing among molecules having 0 or N or F with H. They are as stronger as compared to van der Waals forces of attraction Phenols have hydrogen bonding between molecules which is stronger than van der Waals forces of attraction exisiting between molecules of hydrocarbons. So the phenols have higher boiling points than hydrocarbons.
