NEET Chemistry Properties of Phenols MCQ Question
Consider a diagram depicting the structural features of phenol, where an –OH group is attached to the aromatic ring. Which statement correctly describes the bond characteristics of the carbon-oxygen bond in phenol?
The carbon-oxygen bond in phenol has partial double bond character due to conjugation with the aromatic ring.
The carbon-oxygen bond in phenol is longer than in methanol due to sp3 hybridisation.
The carbon-oxygen bond in phenol exhibits no conjugation with the aromatic ring.
The bond angle around the oxygen in phenol is greater than the tetrahedral angle due to lone pair repulsion.
Correct Answer
Detailed Explanation
In phenol, the carbon-oxygen bond has a partial double bond character because the unshared electron pair on oxygen is conjugated with the aromatic ring. This makes the bond length shorter than in methanol.
