Phenol can be distinguished from ethanol by the reactions with:
(i) \[\ce{Br2/water}\]
(ii) \[\ce{Na}\]
(iii) Neutral \[\ce{FeCl3}\]
(iv) All the above

उत्तर
(i) \[\ce{Br2/water}\]
(iii) Neutral \[\ce{FeCl3}\]
Explanation:
Ethanol does not give any reaction with neutral \[\ce{FeCl3}\] solution while phenol gives violet colour-neutral \[\ce{FeCl3}\]. When phenol is treated with bromine water, 2, 4, 6-tribromophenol is formed as white precipitate. Ethanol does not react with bromine water.
