Draw a resonance structure of the following:
Phenol

उत्तर
Resonance structures for phenol:
Phenol has a hydroxyl group (–OH) attached to a benzene ring. The lone pair on the oxygen can form a double bond with the carbon it’s attached to, pushing the π electrons around the ring. This delocalization creates resonance structures where negative charge is spread over the ortho and para positions of the ring, stabilizing the molecule.
