Question

Phenol is an ortho-para director because the hydroxyl group :
Options
A donates electrons that increase electron density at ortho and para positions favoring nucleophilic attack.
B donates electrons that increase electron density at ortho and para positions favoring electrophilic attack.
Correct Answer
C donates electrons to the ortho and para positions and attracts electrons away from meta positions favoring nucleophilic attack of the ring.
D donates electrons to the ortho and para positions and attracts electrons away from meta positions favoring electrophilic attack on the ring.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The hydroxyl group (–OH) donates electrons (via resonance) to the ortho and para positions, increasing electron density there and favoring electrophilic attack at those positions.

Hint

How does the hydroxyl group direct electrophilic attack?
