The carbon-oxygen bond in phenol is slightly stronger than that in methanol. Why?

Options

  1. APhenol has a more polarizable electron cloud, leading to stronger bonding.
  2. BPhenol has a higher electronegativity difference between carbon and oxygen.
  3. CMethanol has a greater steric hindrance around the carbon-oxygen bond.
  4. DThis is due to the fact that in phenol, conjugation of an unshared electron pair over oxygen with an aromatic

Correct answer

D. This is due to the fact that in phenol, conjugation of an unshared electron pair over oxygen with an aromatic

Step-by-step solution

Correct Option is : (D) This is due to the fact that in phenol, conjugation of an unshared electron pair over oxygen with an aromatic ring results in partial double bond character in carbon-oxygen bond.
