Difference between phenol and alcohol

Property	Phenol (C₆H₅OH)	Alcohol (C₂H₅OH)
Odour	Typical phenolic odour	Pleasant alcoholic odour
Nature, reaction with alkali	Acidic, dissolves in sodium hydroxide forming sodium phenoxide.	Neutral, no reaction with alkalies.
Reaction with neutral FeCl₃	Gives violet colouration due to formation of complex compound.	No reaction.
Reaction with halogen acids	No reaction with halogen acids.	Forms ethyl halides.
Oxidation	Pink or brown colour due to formation of quinone and phenoquinone.	Undergoes oxidation to give acetaldehyde and acetic acid.
Reaction with HCHO	Forms polymer (bakelite).	No reaction.
Liebermann's nitroso reaction	Positive.	Does not show.
Coupling with benzene diazonium chloride	Forms azo dye.	Does not form any dye.
