Phenol has an OH group attached whilst benzene has no side groups. The OH is electron donating, the P orbital on the Oxygen overlaps with the delocalised system of the benzene ring, increasing its electron density, making it a stronger nucleophile and more prone to electrophilic attack. small mermaid clip art
