| Video Discription | In phenol -OH group is directly bonded to benzene. The lone pair of oxygen can interact with the delocalised pi system of benzene and resonance stability is extended to C-O bond. This makes the C-O bond very stable and phenol does not take part in substitution and elimination reactions like alcohol. Therefore phenol will have significantly fewer reactions compared to alcohol, since both alcohol's C-O and O-H bonds can be broken. Let's compare the reactivity and types of reaction for alcohol and phenol. For alcohols: Types of reaction when C-O bond is broken include nucleophilic substitution and elimination. Types of reaction when O-H bond is broken include oxidation (C-H bond is also broken), neutralisation and condensation. For phenols: Since C-O bond is resonance stabilised and not broken, there is no nucleophilic substitution and elimination. O-H bond can still be broken hence phenols can take part in neutralisation and condensation reactions.
