Properties of Ethers

Reimer Thiemann Reaction

Phenols react with chloroform in the presence of sodium hydroxide (or potassium hydroxide) solution followed by acidification to give hydroxy aldehydes.

Reimer Thiemann Reaction


Similar to alcohols, phenols react with carboxylic acids to give esters.

Ethers: Esterification

Coupling Reaction

Phenols react with aromatic diazonium salts in slightly alkaline conditions to give azo compounds. These azo compounds are brightly colored and are used as azo dyes.

Coupling Reaction


  • Phenol is used as a disinfectant.
  • It is also used in the synthesis of polymers.
  • Phenols are used in the synthesis of many organic compounds.
  • Substituted phenols are used in dyeing and tanning industries.
