Phenols & their Properties | F.Sc | MDCAT I NCERT | CBSE Board | JEE | NEET I Wajid Ali Kamboh

In this lecture, we explore Phenols — aromatic compounds containing hydroxyl (–OH) groups attached directly to a benzene ring. You’ll learn their structure, preparation methods, physical properties, and acidic behaviour in detail with diagrams and mechanisms.

✅ Topics Explained:
Introduction to Phenols – Definition, discovery, and examples (Phenol, o-Cresol, Benzyl Alcohol)
Nomenclature of Phenols (Catechol, Resorcinol, Hydroquinone, Picric Acid, etc.)
Methods of Preparation:
From Chlorobenzene (Dow’s Process)
From Sodium Salt of Benzene Sulphonic Acid
Physical Properties:
Colour, odour, melting & boiling points
Solubility trends and hydrogen bonding
Acidic Behaviour of Phenol:
Comparison with carboxylic acids, water, and alcohols
Ka and pKa values
Reaction with NaOH and Na to form sodium phenoxide
Resonance stabilization of phenoxide ion (reason for higher acidity)

📘 Also Covered:
Why phenol is more acidic than alcohols
Amphoteric and weakly acidic nature of phenols
Resonance structures of phenoxide ion

✨ This lecture is highly useful for Class 12 Chemistry, FSc, CBSE, NEET, JEE, MDCAT, and other competitive exams.
