Protonated alcohols react in this manner Protonated alcohols as electrophiles
Based on the cleavage of O–H and  C–O bonds, the reactions
of alcohols and phenols may be divided into two groups:
Rationalised 2023-24
205
Alcohols, Phenols and Ethers
(a)  Reactions involving cleavage of O–H bond
1 Acidity of alcohols and phenols
(i) Reaction with metals: Alcohols and phenols react with active
metals such as sodium, potassium and aluminium to yield
corresponding alkoxides/phenoxides and hydrogen In addition to this, phenols react with aqueous sodium
hydroxide to form sodium phenoxides
