Distinguish 1°/2°/3° alcohols with ZnCl₂ + conc. HCl — turbidity speed tells the grade.
Jones reagent (CrO₃/H₂SO₄) oxidizes 1° & 2° alcohols — green Cr³⁺ appears.
Classic colour test: 1° red, 2° blue, 3° colourless — distinguishes alcohol classes.
CAN reagent gives red colour with alcohols & phenols — quick positive test.
Neutral FeCl₃ gives violet/green/blue colour with phenols — characteristic test.
Bromine water decolourises with phenols (white ppt of tribromophenol) & unsaturation.
Phenol + NaNO₂ + H₂SO₄ → blue/red Liebermann colour reaction for phenols.
