Alcohols, Phenols and Ethers
13 lessons112 min7 simulations10 practice questions
Alcohols, phenols and ethers are the organic compounds built around a C–O single bond: –OH on an aliphatic carbon, –OH on an aromatic ring, or oxygen bridging two carbon groups. The chapter classifies and names them, relates their structure to boiling point, solubility and acidity, and works through their preparation, the reactions that break O–H or C–O bonds, oxidation, ring substitution in phenols and anisole, and the two alcohols made on an industrial scale.
Also called: alcohols · phenols · ethers
